2 ISP lines -> 2 networks -> 1 RB750

RouterOS General
1

Greetings all..

Got a little problem that I have been tinkering around with.

I have 1 RB750 of which dials 2 seperate PPPoE DSL lines now the mission is to have 192.168.20.0 go out via PPPoE-1 and the 192.168.30.0 go out via PPPoE-2 (both for internet access).

At this moment I have created 2 bridges; bridge1: Ether 3, Wlan1 // and bridge2: ether2, Wlan2(Virtual AP) so bridge 1 will use PPPoE-1 and bridge 2 will use PPPoE-2

I have followed guides and have done this so far

/ip firewall nat

 1   chain=srcnat action=masquerade out-interface=PPPoE1

/ip firewall mangle

 0   chain=prerouting action=mark-connection new-connection-mark=ISP1_conn 
     passthrough=yes src-address=192.168.20.0/24 

 1   chain=output action=mark-routing new-routing-mark=to_ISP1 passthrough=yes 
     src-address=192.168.20.0/24 connection-mark=ISP1_conn

I have added this to the routes
/ip route

 0   add gateway=PPPoE1 routing-mark=to_ISP1

I have swapped the Output chain with prerouting to test and unfortunitly I cannot connect to the internet, I seem to be able to Ping 8.8.8.8

Guides I have seen

Thanks for the help ladies & gents
