[RedHat] ARP issue

Hello,

I am setting up a new RedHat server with two network interfaces.
These interfaces are on different subnets, and connected to the same firewall.

I'm trying to reach a remote IP.
It works fine from the first interface.

The second interface however, is making ARP requests instead of contacting the default gateway.
Using the same cable, and a laptop with the same IP setting as this second server interface, I can join the remote IP, so I would say it is not a connectivity/firewall issue.

I have tried several things without success so far

Any idea?

Thank you :slight_smile:
