For testing purposes I created an lxc CT with one network card

Code: 
IP: 10.10.10.224/24
GW: 10.10.10.1

route inside CT

Code: 
# ip route show
default via 10.10.10.1 dev eth0
10.10.10.0/24 dev eth0 proto kernel scope link src 10.10.10.224

Then from proxmox gui I change the gw from 10.10.10.1 to nodes public IP, routes show:

Code: 
# ip route show
default via 148.251.xx.xx dev eth0
10.10.10.0/24 dev eth0 proto kernel scope link src 10.10.10.224
148.251.xx.xx dev eth0 scope link

than from proxmox gui I change the GW from 148.251.xx.xx back to 10.10.10.1, routes show:

Code: 
# ip route show
default via 10.10.10.1 dev eth0
10.10.10.0/24 dev eth0 proto kernel scope link src 10.10.10.224
148.251.xx.xx dev eth0 scope link

now when I try to change back from 10.10.10.1 to 148.251.xx.xx I can not. I guess because proxmox never deletes the following route

Code: 
148.251.xx.xx dev eth0 scope link

The only way to get rid of this is deleting the network interface.
 
Can you post your pveversion -v? I could not reproduce it here.

Can you try it with pve-container 2.0-26 from pvetest repository?
 
Could reproduce it and will look into it.
