How to configure a bridge?

Hello!! Slight smile

In my home network, I have a mini PC with two ports running Proxmox and a virtualized Sophos Firewall Home Edition.

I have purchased a mini PC with four ports to replace the one I currently have. While I wait for it to arrive, I decided to do some testing with a VirtualBox virtual machine where I simulated a WAN port and a LAN port. The WAN port receives the IP 192.168.3.37 via DHCP, and the LAN port has the IP 172.16.16.4.

Next, I added two more virtual NICs so that in Network > Interfaces, the two new ports appear.

My intention is to use one port for the WAN and the other three for the LAN. Following the official documentation:

https://docs.sophos.com/nsg/sophos-firewall/20.0/Help/en-us/webhelp/onlinehelp/AdministratorHelp/Network/Interfaces/NetworkBridgeInterfaces/index.html

I tried to create a bridge to have the three ports with the same IP 172.16.16.254, and here's a screenshot of the configuration:

When I save the configuration, I lose access to the firewall. To regain access, I have to perform a factory reset.

What am I doing wrong?

Kind regards!! Slight smile
