No internet access after installing second nic

[MultiChr]

Hello,

 

I currently upgrade my network to use 2.5 Gbit and while doing so I installed a 2.5 Gbit nic in my Unraid server. Everything looks fine except my Unraid has no internet access anymore.

I do have 2 enabled network cards at the moment: eth0 is the new 2.5 Gbit card and eth1 is the 1 Gbit onboard card.

 

From my point of view it looks like I have the wrong network routes. I already tried to delete and recreate them but the webinterface doesn't let me delete them.

 

Trying to reach anything outside of my own LAN I get the following error:

root@Apollo:/# ping 1.1.1.1
PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.
From 192.168.55.14 icmp_seq=1 Destination Host Unreachable

 

The important part: It's trying to reach the internet via 192.168.55.14 which is assigned to the old eth1 interface which isn't connected. It should take the 192.168.55.2 (eth0).

 

I've attached the diagnostics if needed.

Remove the gateway from eth1, only eth0 should have a gateway set.
