it seems you suggest using packet marks to tell what to go where.


so lets say my 1st wan gate way is:
192.168.1.1
and my second is:
192.168.20.1
and i want to use ether 3,4 and 5 as a local lan
idk no idea what a good local internal range for about 20 devices needs to be

how would i set this up then?
/ip address
add address=192.168.1.1/24 network=192.168.0.0 broadcast=192.168.0.255 interface=ether3
add address=10.111.0.2/30 network=10.111.0.0 broadcast=10.111.0.255 interface=ether1
add address=10.112.0.2/30 network=10.112.0.0 broadcast=10.112.0.255 interface=ether2

i could just try match my 2 wan connections routers to match the range.
thanks for the help i’ll let you know the end result.

any good guides on QOS?
