Mikrotik Remote Access via Multiple WAN Links | Syed Jahanzaib Personal Blog to Share Knowledge !

Posted by jpluimers on 2020/11/04

Multi-WAN routing always involves marking incoming connections to the replies go out on the same connection: [WayBack] Mikrotik Remote Access via Multiple WAN Links | Syed Jahanzaib Personal Blog to Share Knowledge !

# Mirkotik IP Firewall Mangle Section
/ ip firewall mangle
# Mark traffic coming via WAN-1 link
add chain=input in-interface=WAN1 action=mark-connection new-connection-mark=WAN1_incoming_conn
# Mark traffic coming via WAN-2 link
add chain=input in-interface=WAN2 action=mark-connection new-connection-mark=WAN2_incoming_conn
# Mark traffic routing mark for above marked connection for WAN-1 , so that mikrotik will return traffic via same interface it came in
add chain=output connection-mark=WAN1_incoming_conn action=mark-routing new-routing-mark=to_WAN1
# Mark traffic routing mark for above marked connection for WAN-2, so that mikrotik will return traffic via same interface it came in
add chain=output connection-mark=WAN2_incoming_conn action=mark-routing new-routing-mark=to_WAN2
# Finally Add appropriate routes in ROUTE section
/ ip route
add dst-address=0.0.0.0/0 gateway=1.1.1.2 routing-mark=to_WAN1 check-gateway=ping
add dst-address=0.0.0.0/0 gateway=2.2.2.2 routing-mark=to_WAN2 check-gateway=ping

RB450G and “..could not get answer from dns server” – MikroTik

Posted by jpluimers on 2020/07/06

[WayBack] RB450G and “..could not get answer from dns server” – MikroTik: I do not see a default route. It would be the route with “dst-address=0.0.0.0/0“.

Research list: machine sometimes not visible on LAN

Posted by jpluimers on 2019/04/08

When one of the machine isn’t active for a while it seems to disappear. Even when it’s active some of the machines have intermittent errors pinging it as like every 10-30 seconds one of these ping results appear:

92 bytes from tl-er5120 (192.168.71.1): Redirect Host(New addr: 192.168.71.193)
Vr HL TOS  Len   ID Flg  off TTL Pro  cks      Src      Dst
 4  5  00 0054 05de   0 0000  40  01 644d 192.168.71.108  192.168.71.193

Sometimes even a simple

Request timeout for icmp_seq 6900

So I need to dig into  ICMP “Redirect Host” .

It might be a simple ARP thing like mac mini – Why the different results for ping? Or why is the Time Capsule getting involved? – Ask Different [WayBack] but like usual stuff I bump into is of a more complex kind so I’ve archived at least these:

Just in case I move away from Mikrotik

Posted by jpluimers on 2018/07/02

Mikrotik has great hardware, great firmware (if you have the right builds), but notoriously bad documentation and a not so great software release and testing process.

So I might consider switching away, so here are some threats that might lead to alternatives:

I use ubnt edgerouters, great bang for buck. My ER Pro-8 has been up for 8 months (no reboots) and hasn’t missed a beat, rock solid ipsec vpn. I looked at microtik, but found the edgerouters slightly easier to configure.
