Hi,
I try to setup OPNsense in proxmox for couple of days now, but I can't figure out why it's not working. First let me start with how the "network layout" looks like:
ISP -> ISP's router which is set to modem mode (so it shouldn't do anything other than passing through the connection) -> proxmox -> OPNsense (which is installed as a VM). First I created the Linux Bridges for the ports on my PC, then I only assigned two network devices to the VM (vmbr1 and vmbr2), just so that I can set it up more easily and later on I will add the rest of the network ports.
Then in OPNsense I assigned vtnet0 to WAN (which is actually my WAN port) and vtnet1 to LAN and I also changed its static IP to 10.0.0.1/24
Here is a link (https://imgur.com/a/OQyKAAK) to the screenshots for all the points I mentioned earlier
But the issue is that for some reason OPNsense can't get an IP from my ISP. Or actually I can see an IP there, but for some reason it can't add that IP to the interface? I grabbed the logs from Interfaces -> Point to Point -> Log file and found some interesting entries there:

I think 77.XXX.XX.104 would be my IP, but then it doesn't do anything with it.
I couldn't find anything online about the "Adding IPv4 address to pppoe0 failed: File exists" or the "Removing IPv4 address from pppoe0 failed: Can't assign requested address" messages (but probably I just missed it), I am not sure what they mean.
Does anybody know what I messed up in this setup?
Thanks for the help in advance.
