hEX S in kernel panic reboot loop - I have reset router and re-applied configuration step-by-step and I found out that everything works until I enable OVPN Server - when I do that router starts to reboot (it comes online for 10-15 seconds - in this time I was able to make export of config :) )

Colleagues, is it a supported setup to use VRRP with some dummy private IP addresses on "WAN" side and just add (single) public IP on VRRP interfaces (along side with private IP of course)?

Thank you,

Hi! I am using mANTbox AX 15s in such configuration - to make a simple bridge between two buildings - 300m distance. Yes, we have some leaves in between but I am quite sad about performance - we are not able to get more than 200/300 Mbps over this link. I stumbled upon your post by searching the opt...

Thank you very much for explanation.

While waiting I was able to set it up on 5300 MHz eeeece (20/40/80/160MHz)... And I am happy also with 1 minute waiting for DFS. I would like to know if there is a possibility to do something about TX power - can it somehow be manually increased?

Hi! I am quite new to new ROS7 wifi interface - I have bought two L22UGS-5HaxD2HaxD devices and I would like make point to point link with 5GHz AX - I am wondering if I can use 20/40/80+80 or 20/40/160MHz (or it supports only 20/40/80MHz) channel width? Any idea which frequencies should be chosen to...

Hi!

Something changed from beta firmware(s) (at least 7.11beta2) to RC in relation to OpenVPN - RC version has problems with more than 170 OVPN connections ...
I reverted to 7.11beta2 and everything works great.

Hi!

It is a simple DST-NAT where DST address is my public IP that I am receiving over VPN (udp on port 443) that is DST NATed to IP I am receinving in "hosting network".

OVPN works much better!!

I can confirm it too... Waiting so long for this fix! Thank you MikroTik!

I would like to thank Anav who helped me solving it out. Long story short - Wireguard (service) that runs on MikroTik prefer main routing table and binds to IP address that is in the same subnet as gateway in main routing table, even if you try to use mangle rule to make it go via other routing tabl...

Old school tools still can do wonders.

Pen and paper.
Make a drawing.

manojlovicl

A diagram would have made this much clearer. :-( For example, is the SSTP VPN a connection to the MT device/router? or to the Router in front of the MT and then the VPN connection is fed to the MT as a WAN port with an IP address and gateway?? This router is a standalone router connected with 1 cab...

manojlovicl

Since you have multiple wan, mangle might be needed. Read this thread from anav. Section 9 B https://forum.mikrotik.com/viewtopic.php?t=182340 Do you think - as there is UDP that I will need a combination of packet mark + routing mark? I already have a "general" output routing mark mangle...

manojlovicl

Wireguard shouldn't need mangle. I also thought it will be simple... But look - this is output filter rule for logging only: output: in:(unknown 0) out:br-lan, connection-state:new proto UDP, 10.x.y.z:443->PUBLICIPOFMYPHONECLIENT:7736, len 120 Instead of private IP there should be public IP as a so...

It is a router (A) currently located as guest in a NAT-ed network. It has (private) IP in that network. From here I do a VPN to another router (at our ISP) where I have the option to route public IP to the router (A) - this part works. I can access router (A) via Winbox by using public IP so output ...

Hi! I have a case, that router routes some traffic over VPN (over which I get public IP address) - I want to use this public IP as Wireguard endpoint. The problem is that clients try to connect to IP (I can see packets) but responses from MT Wireguard service are going back by using default routing ...

Hi! In this great video (https://www.youtube.com/watch?v=T1Dyg4_caa4), colleague Druvis Timma explains how to configure Let's Encrypt on MikroTik and also touches the problem about renewal and opening of the router's port 80 for Let's Encrypt verification. After following the instructions I found ou...

manojlovicl

No, it is completely fine - I also think that revealing such information could lead to bigger problems. Do not worry, my first thought was that maybe anyone knows if I do not know maybe by going through SNMP with DUDE can give any better results... All good! Thank you! Tutto bene!

Luka

manojlovicl

Well, it can be even more complicated - that you need to help a company where someone left and there is no documentation but yes, I understand what you intended to say. It is quite a basic thing so I think I will be able to resolve most of the things by snmp walk output. Thank you colleagues for you...

[…] is possible to recover router configuration if you […]you do have SNMP read-only password and router access ? […] If for "and router access" you mean that you can query by SNMP the device, simply, not. So you think that I need to find things out by checking the output of snmp walk and...

manojlovicl

SNMP walk is what I did but I am not completely sure there is everything - I was thinking if there is any other way to somehow use this SNMP read-only community string to get to full config... Thank you for your answer!

manojlovicl

Hi!

I would like to know if anyone can tell me if it is possible to recover router configuration if you do not have (winbox, ssh...) password but you do have SNMP read-only password and router access?

Thank you,

I would like to run it on CHR - the space and ram is not a problem there but do you have any idea how to solve this chown issue?

Colleagues, can you please implement the option to declare host down only after some failed checks? So can Failed tests be used as trigger for Down? That would be great.

I have two routers that are doing BGP (they are made redundant by using VRRP ...)

manojlovicl

Just don't forget you need to use policy routing to properly choose an outgoing route via the corresponding WAN for each of the two server processes (SSTP and HTTPS). /ip route rule is enough, you don't need to fiddle with /IP firewall mangle. What if I have two public IPv4 addresses on same WAN in...

Netwatch is a great feature but sometimes there is a need to wait more than just one lost ping to trigger some action ... I managed to solve it by scripting an "extension" to Netwatch - hope it is useful to someone: https://luka.manojlovic.net/2019/06/01/mikrotik-netwatch-enhanced-updated-...

manojlovicl

you can now specify many headers, separated by comma:
