I thought it best to post here as I posted similar previously in general and I guess the guys got tired of my naivety

My setup:

ether1 -> fibre
ether2 -> dsl
ether4 -> lan - > switch -> towers

ether4 -> 192.168.102.102 with DHCP server for internal lan
ether4 -> 192.168.192.100 for towers & mikrotik devices which are in the 192.168.192.0 network

I have setup route marking to split traffic between fibre and dsl depending on IP range, before I added this I was able to access the 192.168.192.0 network from the 192.168.102.0 network but cannot anymore. Ideally I would like to have the towers on ether3 and not through the switch, I've tried routing it but without success.

Some guidance if you please.

Thanks.

It sounds as if the route marking means that each IP group no longer sees the route to the other subnet. You can either add route rules so that lookups for certain subnets always occur in main or you can add routes to each subnet in the other VRFs.

I have tried again numerous times since your post but I don't see the light, would you mind terribly giving an example please?

Try uploading your config from /export compact and also your routing table.

Sorry been running around alot lately.

Well you are correct, if I disable the address list for mark routing I'm able to connect to the other subnet. The mark routing also poses another problem with my port forwarding, connections are slow and laggy.

Is there another way to split traffic based on IP range?
