Change network interfaces


Mar 19, 2023
after I installed proxmox, I add a new PCIe card with 4 NICs and my configuration look like


proxmox has actually and the 254 gateway is opnsense. It works, but I want to use vmbr0 for WAN in opnsense and vmbr1 as my admin network. Can I just set the CIDR and Gateway for vmbr1 and clear vmbr0? After that I have to change the network for my vms and containers and also configure opnsense, but is this the right way, or do I have to configure it in an other way?
