Upon my first installation of Proxmox, I entered the LAN parameters into the setup wizard. This was assigned to eth0+vmbr0. Everything worked fine upon the initial boot of the host.
I attempted to change the network setup using the web interface. My network uses eth1+br1 for the LAN connection. This is just a cosmetic change so that the new server uses the same conventions as my other servers.
Using the "Network" tab for the host, my steps were:
In the /etc/network/interfaces file, I see the correct gateway being used for vmbr0. The web interface shows this correct gateway on in the "Network" page.
I believe there is a conflict between the network configuration file on the host and the verification data used by the web interface.

Using the "Network" tab for the host, my steps were:
- Edit vmbr0 so that it uses my WAN parameters. The "Gateway" in the "Edit: Bridge" dialog box was replaced with the WAN gateway.
- Reboot the server for the changes to take effect.
- Logged into the server using the WAN IP address. Everything is still working fine.
- Attempt to "Create" a bridge vmbr1 for the LAN connection. In the Edit:Bridge dialog box, I entered the LAN's gateway (which used to be assigned to vmbr0, but was changed in step 1).
- Error message pops up: Parameter verification failed (400). Gateway: Default gateway already exists on interface vmbr0. This is not true.
In the /etc/network/interfaces file, I see the correct gateway being used for vmbr0. The web interface shows this correct gateway on in the "Network" page.
