I got one server. this server has two interfaces named enp30s0 and enp31s0.
enp30s0 is connected to a modem to internet with the IP address 10.66.64.130
enp31s0 is connected to a huge Lan with lots and lots of subnetworks like 10.66.0.1 10.66.1.1 10.66.2.1 and so on, with the IP address 192.168.0.106.
I got a second route table to add the gateway of enp31s0 so other subnetworks can see me.
###RUTE TABLE###
post-up ip route add 10.66.64.0/24 dev enp31s0 src 10.66.64.130 table rt2
post-up ip route add default via 10.66.64.254 dev enp31s0 table rt2
post-up ip rule add from 10.66.64.130/32 table rt2
post-up ip rule add to 10.66.64.130/32 table rt2
Everything works but if from the server I do something like a
ping 10.66.0.165
the server goes through the enp30s0 and not through enp31s0.
1?: [LOCALHOST] pmtu 1500
1: 192.168.0.1 3.226ms
1: 192.168.0.1 0.489ms
2: 192.168.1.254 1.538ms
3: 192.168.1.254 1.343ms pmtu 1492
I need that the address from the server to 10...* goes through enp31s0.
How can i achieve that?

@slm There is something else, but that might do, depending on situation. I have not yet though well about the question, and today wont be probably a day for it.
