eth1 LAN vmbr1 configuration while keeping eth0=>vmbr0 alive

Two nics ,
eth0 public IP => vmbr0
eth1 LAN from pfsense with public IP

The vmbr0 was set up automatically on install

How to properly set up vmbr1 for eth1 for use with VM's while keeping eth0 open - I have 10 TB bandwidth allowed on eth0

I have connection and all nics are up on both machines.

Thanks, Rick
