Hello list,
I have a networking question that I can't understand for.
I have the Debian 11 host with two ethernet cards.
There is public IP and gateway for each ethernet card.
(they are public IPs from two different net address blocks.)
Say:
eth0 ip: 193.36.132.10 gw: 193.36.132.1
eth1 ip: 5.255.106.10 gw: 5.255.106.1
The system's default gw is the first one (eth0).
When clients from outside access eth1 ip (such as HTTP access), they can
reach there.
But, the returned packages from debian server to clients are always
coming from eth0 gw.
I expect the returned package also come from eth1 gw (since clients are
accessing eth1 address).
How can I setup this? Thanks for any hints.
regards
Corey H
