This is easy, just set up 2 new routing tables and add rules to assign the
packets to the correct one.
Let's say you have
eth0: 1.2.0.2/30 (gateway 10.2.0.1)
eth1: 192.168.0.1/24
eth2: 192.168.1.1/24
eth3: 1.3.0.2/30 (gateway 10.3.0.1)
Then you do something like:
ip rule add from 192.168.0.0/24 table 101
ip rule add from 192.168.1.0/24 table 102
ip route add 192.168.0.0/24 dev eth1 table 101
ip route add 192.168.1.0/24 dev eth2 table 101
ip route add 127.0.0.1/8 dev lo table 101
ip route add default via 10.3.0.1 dev eth3 table 101
ip route add 192.168.0.0/24 dev eth1 table 102
ip route add 192.168.1.0/24 dev eth2 table 102
ip route add 127.0.0.1/8 dev lo table 102
ip route add default via 10.2.0.1 dev eth0 table 102
(it's likely I forgot some detail or have a typo there, it's just an example)
