Problem to make two interfaces work on linux in Azure

Question

I had problem with work two interfaces on Azure Ubuntu.

Interfaces eth0, eth1.

After adding default routing for eth1 working now:

eth0 in both ways (normally)

eth1 one way only(outbound)

I can't connect to eth1 from external. NSG had all port open etc (same like eth0).

Answer 1

Routing added for eth1 and solved.

ip route add 10.1.0.0/24 dev eth1 src 10.1.0.1 table rt2

ip route add default via 10.1.0.1 dev eth1 table rt2

ip rule add from 10.1.0.4/32 table rt2

ip rule add to 10.1.0.4/32 table rt2

file /etc/iproute2/rt_tables:

1 rt2
