routing with multiple WAN interfaces

RouterOS General
1

I am using 1100ah and my configuration currently have three WAN links and one LAN.

The idea is following:

  • WAN link 1 - main internet access link for clients
    WAN link 2 - backup internet access link
    WAN link 3… - specific point to point links

WAN link 1 is working fine, I have created NAT (masquerde) and all clients are using this port nicely.
I have also created port forwarding (dst-nat) so my mail server can be contacted through WAN link 1.

Now I want to activate WAN link 2.
The idea is to use this WAN link 2 as a entry point for VPN and alternate SMTP route.

I have configured WAN link 2 correctly (I belive) and I can ping the IP adress of WAN link 2 both from the internet and from LAN.
The problem is that when I try to create port forwarding (like I already did on WAN link 1) it simply does not work.

I have tried to read manual and browse through the forum archives but without success; there are plenty of situations where people agregate two or more LAN links for internet use; but I have not found examples where traffic from the internet is forwarded into LAN from more then one WAN link.

Any ideas what am I doing wrong or what and where I have to read is more then welcome.

this is great tutorial :slight_smile:

and it solved my problem (and I did not have to use google translation :slight_smile:

my conclusion is that mikrotik is a great device, but not for the people with weak heart
it can be configured to do literally anything you just need to know EXACTLY what you are doing

thanks
