Prox still uses old gateway ip

[aurel81]

Hey I was wondering why one prox ve cant access the wan in my setup ( 1 of 3).
Some digging showed me, that it tries to connect to 192.169.0.1... the gateway/subnet it was connected to during installation and although it gets ip from the current vlan... the other 2, connected to the same vlan try to reach for the corresponding gateway...und it works

Any idea how to fix it?

Change the network config to use the correct GW?

Otherwise, please provide more infos! What is the current network config of the host? (cat /etc/network/interfaces) and what is actually applied? (ip a, ip r)

Looks to me, that your DNS server is incorrect; not your gateway.
You can adapt it in: /etc/resolv.conf
