Hi everyone, I have a very strange issue that I can't figure out how to solve
vmbr0 is the lan bridge, I have another port (2.5Gbit/s) on the router that I wanted to switch along with the main one (10Gbit/s), as you can see from the picture, so that I could connect the ubiquiti AP to that (as I am doing now with the hardware switch) to use the 2.5Gbit (my switch has only 1/10 ports unfortunately)

If I configure it like in the picture and. plug the access point in it, it works halfway, I can actually surf the web but DHCP breaks and some devices won't receive the DHCPOFFER that is supposedly sent by the OPNsense router that is on the machine (I can see it being sent via tcpdump on proxmox on the network interface) and go into a loop of requesting the IP address.

tcpdump on proxmox, the DHCPOFFER is never received by the device plugged in
The issue is very similar to this thread https://forum.proxmox.com/threads/h...and-wire-it-to-vmbr0-to-expand-my-lan.112254/ as I've been trying to do the same exact thing, but openvswitch doesn't seem to be the solution for me (i.e. has the same issues)
I've tried with both openvswitch and linux bridges, and also tried on mikrotik chr and the same behaviour appears. It also happens if I connect a computer instead of the access point, so it's not the ubiquiti hardware
I believe this might even be a software bug in proxmox or a hardware fault, as there should not be any particular reason for this behaviour![Frown :( :(](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
