Greetings,
Looking to see a fully working config for a /29 network. Maybe even different examples if you have them. Rough network diagram attached.
Can someone share a full working /29 config

Re: Can someone share a full working /29 config
your diagram/networks It's fine as it is but really depends on what you are doing and trying to achieve, but i will do it differently because public ip is very scarce i will conserve it if i have to as much as possible, if some servers or workstation can be behind a NAT i'll do it.

Re: Can someone share a full working /29 config
You can create a new bridge and put Ether1-Ether4 in it. Assign x.x.x.178/29 as /ip/address the new bridge, and the desired static assign on servers. Assuming you have the default firewall/config, you need to add the new bridge interface to the "WAN" interface list (under Interfaces > Lists) to protect the router.
Same approach is possible using VLAN as the WAN, instead of new bridge. You need to be using vlan-filtering=yes in bridge, assign x.x.x.178/29 to a new VLAN, and tag ether1 to ether4 with the new VLAN ID. This be useful if you servers need both the WAN and LAN (assuming servers are VLAN-aware).
@loloski advice isn't bad and some way also safer (since you'd defining the ports needed). Basically, approach is you essentially assign all the IPs the router and use either action=dst-nat for ports, or even action=netmap to map all ports to specific host in /ip/firewall/nat (e.g. NAT defines the mappings, including which of the public IPs to map it to). The servers only see there LAN address in this case & all access is gated through the Mikrotik router.
In all cases you'd need an /ip/route for 0.0.0.0/0 to x.x.x.177.

Re: Can someone share a full working /29 config
I have a CCR2004, it came without a config. I want this monolithic ip per server setup to support FTP server. If I'm doing the simple setup as mentioned in the first paragraph, what do I do with the sfp+1 interface? If .178 is assigned to the bridge, can it also exist on the sfp+1 port?Assuming you have the default firewall/config, you need to add the new bridge interface to the "WAN" interface list (under Interfaces > Lists) to protect the router.
Right now I have
/interface list member
add interface=bridge1 list=WAN
/ip address
add address=x.x.x.178/29 interface=bridge1 network=x.x.x.176
>>> do I add this??: add address=x.x.x.178 interface=sfp-sfpplus1 network=x.x.x.177
/interface bridge port
add bridge=bridge1 interface=ether1
add bridge=bridge1 interface=ether2
add bridge=bridge1 interface=ether3
add bridge=bridge1 interface=ether4
>>> do I add this??: add bridge=bridge1 interface=sfp-sfpplus1
Re: Can someone share a full working /29 config
No. Leave the address as /29./ip address
add address=x.x.x.178/29 interface=bridge1 network=x.x.x.176
>>> do I add this??: add address=x.x.x.178 interface=sfp-sfpplus1 network=x.x.x.177
But you need a route:
Code: Select all
/ip route add gateway=x.x.x.177
If you want to make it a switch for the WAN, then yes:/interface bridge port
add bridge=bridge1 interface=ether1
add bridge=bridge1 interface=ether2
add bridge=bridge1 interface=ether3
add bridge=bridge1 interface=ether4
>>> do I add this??: add bridge=bridge1 interface=sfp-sfpplus1
Code: Select all
/interface bridge port add bridge=bridge1 interface=sfp-sfpplus1Re: Can someone share a full working /29 config
Does this look like it would work? Any advice? (I should mention that the LAN network is needed only for the various management interfaces. I want to VPN in to this network which I will ask about in a different thread.)

There is no firewall is main thing.
See https://help.mikrotik.com/docs/display/ ... t+Firewall
but personally the default firewall is better than the docs:
Also, if you don't have IPv6, you may want to disable it:
