I have a new mAP which I want to use in the reverse of the configuration that it's normally used in. In other words, the ethernet cable will connect my LAN to the mAP port 1. And the WiFi will connect to my phone "hotspot" as a client. I am trying to create a backup route in case my cablemodem goes down. Since the mAP will be on the outside of my firewall it should pass through packets. It will be the job of my firewall to route packets to the mAP when the cablemodem is down.
I find the QuiCKSet confusing, so I went to the full WinBox interface (and I have *basic* familiarity with MikroTik). I can access the new mAP from ethernet and wifi side, so that's great. But now I'm stuck.
Has anyone done this before? Is there a guide somewhere that explains how to configure what I want? I thought I could at least figure out how to make the WiFi side into a client to connect to my phone...but I don't even see a "client" mode (under Interfaces > wlan1 > Wireless > Mode)
Thanks
Re: Setup mAP in reverse config from default
In Mikrotik client is called "station".
And there are a few modes available, you want station pseudobridge, see:

Re: Setup mAP in reverse config from default
I've spent around 7 hours messing with my new mAP in total. I just can't get it to do what I want! What's I'm trying to do is:
1. Device acts as a bridge (briding eth1 + wlan1)
2. WLAN1 Acts as station, connecting to my phone's hotspot
3. ETH1 passes the IP config received from the wifi along to the ETH1 port
4. No IP > firewall rules (which shouldn't even make sense for bridge)
I keep getting locked out, resetting it, and trying again....argh
I'm getting stuck around the bridge point. I disabled the default ports in the bridge, and added all of the ports (ETH1/WLAN1) to the bridge. But the WLAN1 just always says disabled port. Why? Can you not add a wlan port to a bridge?
Is the above config even possible with this device? Do I have to make this device into a router?

Re: Setup mAP in reverse config from default
So you want a straight bridge, wireless included, not a router.
Search for full instructions. The basic process is to connect via MAC address, delete the existing configuration, create a bridge and add everything to it, with wireless set up as a DHCP client for connection.

Re: Setup mAP in reverse config from default
Post what you have, see instructions here:
viewtopic.php?t=203686#p1051720
If you want a reference, I have somewhere a hap lite (should be very similar to the map/map lite) with a very simple configuration that I can share.

Re: Setup mAP in reverse config from default
Did you use pseudobridge mode, as mentioned above?
Re: Setup mAP in reverse config from default
Ok, here is the (very, very basic) configuration that you could use as a base:
It is the simplest one I could come up with, it is completely static, in you case you will need to add a dhcp client, but that is easy, once you have it working as static.

Re: Setup mAP in reverse config from default
First of all I didn't realize I could connect by MAC address...wow what a time saver. Thank you.
Next, I'm looking at the script above and I've tried to do each step manually from the WinBOX gui. But I clearly am missing an important concept here...i can't get my head around this:
1. I see you set set a static IP on the device as well. Why? I want this device to get the IP from the WLAN side, and that pass that along to the wired side (so this device is transparent). Is this IP an "EXTRA" ip I can use to connect to the device for further management?
2. Since I want my device to pass the WAN side IP to the LAN side, do I also need a DHCP server to pass along the IP to the LAN side?
3. Since this is a bridge, why do I need a route? Shouldn't everything coming in one side just pass through to the other? Or is this just for the management interface?
The script you posted bridges all the ports, yet it gets an address via DHCP from one side, and has a static IP on the other. How can that be? How can it be a "transparent bridge" if it has different IP's on each side?

Re: Setup mAP in reverse config from default
- Yes
DHCP client sends out broadcast packets when doing DHCP discover and bridge will send these frames out via all member ports. In principle only one DHCP server is necessary per L2 broadcast domain and if there are multiple servers in given L2 broadcast domain (not wrong by itself), it's expected that they all reply with leases valid for a client. - Yes, statically set IP address (specially so if it's from different IP subnet) can be used for management purposes (if you know management IP address, you can connect computer with IP address from the same subnet and you can connect). With Mikrotik this is not needed if you leave MAC Winbox connectivity enabled.
- bridge transparently passes ethernet frames between member ports. This in principle includes also wireless interfaces. So none of DHCP functionality (DHCP server nor DHCP relay) is needed in this case.
However: depending on wireless radio mode things might no be as transparent as we'd wish. If wireless radio is set as station or station-pseudobridge, then wireless interface (or rather: communication with AP) is not transparent, MAC address of wired machine on station side gets lost ... which can upset a few services (e.g. DHCP server if it works with MAC addresses and not with client-ID values).
Re: Setup mAP in reverse config from default
Ok then I have it setup as specified. But something seems strange:
1. I can ping the mAP 's wireless address (received via DHCP), from other hosts on the same subnet. Good!
2. When I tried to connect to the mAP using winbox via the wireless address, it will not connect. Strange?
3. I can NOT ping the mAp's static IP, from host directly connected via the eth1 port. Strange?
4. I can connect to the mAP using the MAC address via the wired eth1 connection. Good!
Do I have to adjust firewall rules to permit something here? Can someone explain why #2 and #3 are happening?

Re: Setup mAP in reverse config from default
Well, the setup I posted is (intentionally) static only, it is that of a device that I use to give wireless connectivity to a device that has only a wired port but is physically in a room where there is not an ethernet cable arriving nearby.
In your case you may want or need to set it with a DHCP client.
In this case the DHCP client will be assigned to the bridge.
The DHCP server should be your telephone hotspot (that acts as an AP).
The issue might be, if you also have a DHCP server on any device connected to the ether1, a conflict of some kind.
As well, devices connected to ether1 that run a DHCP client may get confused from the (added) DHCP server of your phone hotspot.
But since the device on the other side of the cable connected is your "main" router/firewall, you can "stop" the DHCP on its side
Cannot really say if it is possible, but if you can change settings or your phone hotspot (i.e. have a same, known, IP address as gateway), I would think that it would be better to use in your case static settings as well.
BUT it has to be considered how - due to some limitations of the 802.11 standards - the mode=station-pseudobridge is not really-really a complete L2 switch/bridge equivalent, it is complicated, but basically there could be issues with more devices connected to ether1.
An alternative could be to set your map to work as a router (yes, you will have double NAT, but it is (IMHO) largely a myth that it represents a problem).
In this alternate configuration, you would have ether1 and wlan1 routed, you would have the wlan1 running a DHCP client (that would get the DHCP data from the DHCP server of your phone hotspot) and ether1 with a static IP address, the route/gateway would be automatically added from the DHCP data, and all you would have to do would be to set in your main router the map ether1 address as (failover) gateway.

Re: Setup mAP in reverse config from default
We won't know until you post your current configuration for review.Do I have to adjust firewall rules to permit something here?
Re: Setup mAP in reverse config from default
I meant conceptually (since I'm not sure IP firewall rules are even processed between ports that are bridged). But just in case, I added accept rules for in/out/fwd at the top of the list, and no difference.
There must be a reason for this I don't understand.
BUT!!!! It is working, in that traffic is flowing the the mAP as expected. So it works for general traffic, but I can't ping the static IP I set, and can't access the static (wired) IP.

Which leaves us with around 42
other possible reasons (give or take a couple ones).The only way to hopefully find it/them is to actually read your configuration, otherwise we would just make (educated or not) guesses.
Re: Setup mAP in reverse config from default
Ok here's my config. Note that it's built on the default config, so some garbage left over but I think it is harmless. But after being locked out of the mAP so many times, I did not want to reset the config (since the is no serial interface to this device).
Any clues in the below as to why I can't ping the static IP? Or use winbox via the lan/wan IP?

Re: Setup mAP in reverse config from default
Well, which IP address are you pinging?
The bridge has none set.
Only ether1 has one (and it is a /32):
Try running /ip address print and post the output.
Same for /ip route print, this way we can understand what happens with Dynamic settings (coming from DHCP).
Since right now your device is essentially a "dumb switch", it is well possible that no IP is assigned to bridge, a switch doesn't really need one, still you might want to set one for pinging or IP access.
Once you add an interface to a bridge, it loses its own "self-standing" identity and follows the settings for the bridge.
As well, the bridge is not in interface list WAN nor LAN:
As a side note, do not be so sure that the whole set of completely unneeded things you have set right now is harmless (it may be so, but do not assume that).
Having running on the bridge both a DHCP client and a DHCP server (which you shouldn't need) seems to me like a good example of something that may well (before or later) create issues.
Since you have right now an unused interface, ether2, it is a good idea to set it independent, with a static address of (say) 192.168.88.1/24, make sure that it is part of LAN interface-list.
This way you have a "dedicated management port" that you can reach in case connectivity via wlan1 or ether1 is compromised by some "wrong" configuration experiment.

Re: Setup mAP in reverse config from default
I thought that adding the static IP to eth1 was a good idea, so that some bad actor on the WAN side couldn't access. But I don't understand if that is valid for a bridge, or in that case why the mikrotik let me do it 
I got rid of the DHCP server, and moved the static IP to the bridge, and changed the static IP address from /32 to /24. This leads me to my next question...but I think everything is working!!
But I have to test more. Now my left over questions...
1. What does it mean adding /24 onto the field marked "ADDRESS" for this interface? I thought an address was a single value. But adding the /24 (mask bits) I am defining a subnet. Is that "ADDRESS" field actually 2 things combined?
2. Since all ports are bridged, now the outside world can see my WinBox port! That feels dangerous. Do I need to disable this via IP > SERVICES?
3. I've read about ReMON. Is that a "safer" way to manage the mAP from WinBOX tool (since my firewall is a mtik, which connects to this mtik, I'm guessing the neighbor detection would allow me to manage it from inside my LAN).
4. Or does exposing ReMON to the internet cause even more problems? Do I need to add a separate IP (to eth2) and only manage it that way? Seems very cumbersome, but better safe than sorry.

Re: Setup mAP in reverse config from default
0.
ether1 is an interface and it has its own "dignity" and you can assign an address to it.
But when you add it to a bridge, the bridge is *like*
WE ARE THE BORG; YOU WILL BE ASSIMILATED.YOUR UNIQUENESS WILL BE ADDED TO OUR COLLECTIVE. RESISTANCE IS FUTILE.
the individual address of the port looses significance.
Still, the moment you take the interface out of the bridge, its address will become relevant again.
1. Yes.
An address in itself is just an address, you need to also define its network mask.
On Windows and most other consumer network stuff your ether1 address would have been:
IP address: 172.31.246.2
Netmask: 255.255.255.255
In Ros, if you input:
it is the same (missing / parameter) as:
and the result (in /ip address export) will be *like*
i.e the network parameter is added automatically and set to the single address.
If you try:
you will see that (in /ip address export) you will have:
the network now is correct for the /24.
Check on this calculator:
https://www.calculator.net/ip-subnet-calculator.html
to get familiar with the various possible syntaxes.
2. Yes and no
Since the device is now a (dumb) switch it has no way to filter anything.
Though it should be possible to use firewall on the bridge and (say) drop the port Winbox uses (default port 8291) or simply change it to a new "random" one, the hypothetical attacker will now need to know (or guess) 3 pieces of credentials, user, password and port #.
As said, where possible it is better to take one port out of the bridge (and leave it not connected normally) and use it for management via Winbox during configuration and, once you are substantially satisfied with your tests, allow winbox only on that port.
Typically you would have (example):
Many people disable Winbox alltogether and leave only ssh access (as well usually only from connections on a single port, and in some cases - even safer - only allowing management from a single source IP).

Re: Setup mAP in reverse config from default
The input firewall chain still works.2. Yes and no
Since the device is now a (dumb) switch it has no way to filter anything.
However by default the bridge is a LAN interface and input is allowed from LAN interfaces, ie. All ports.
(Input is disallowed from all except LAN interfaces)
You can add (and remove/modify) firewall rules to filter access to the router (eg. by IP address, or from a port removed from the bridge)
