One router and two external IP

RouterOS General
1

I’am little newby, but can you help to solve this situation ?

I have mikrotik router os level4. On the machine the are 6 nic (each nic - is different network) and router is working , i can see internet and from internet people can see me (dst-nat is working)

ethernet1. ip address=10.10.1.1
ethernet2. ip address=10.10.2.1
ethernet3. ip address=10.10.3.1
ethernet4. ip address=10.10.4.1
ethernet5. ip address=WAN IP , real ip address which i get from isp interface name=WAN1
ethernet6. ip address=WAN IP , real ip address which i get from isp interface name=WAN2

my goal is next…

ethernet nr. 1 and nr. 2 must go to the internet trough interface nr. 5 WAN1
and
ethernet nr. 3 and nr. 4 must go to the internet trough interface nr. 6 WAN2

one word said eth nr.1 and 2 must be identified on the internet under its own real ip (wan1 real ip address),

in the nat i have masquerade for wan1 and wan2…

how to make it work ?

thanks.

U need to use mangle to mark routing of interface 1 and 2 with wan1. And the same for the others.

Try to search mark routing in the wiki.

It’s easy to do this and there are several examples in the wiki. You could read load balancing in the wiki.
