Hi.
I installed OPNsense as a VM in Proxmox 8 to practice with this firewall. It gets an IP (its main WAN port) from my physical router which manages my home LAN.
I set a WAN pass rule in OPNsense to allow my pc on my physical LAN to get access both to OPNSense GUI, VMs and physical machines on its internal LAN.
Of course, I also set a route up on my router for the Opensense VM's LAN. I can ping the laptop connected to a Proxmox NIC that is on the OPNSense LAN.
Here is the interfaces setup:
vmbr3 is set on a USB-ethernet device I added as an additional NIC to my Proxmox machine in order to pratice with dual WAN failover in OPNsense, or other routers I have been tinkering with. Anyway, nothing was connected to this usb nic when I try to RDP to my laptop.
However, when I connect to the laptop via Windows RDP a problem occurs that I can't still manage to get my head around, after I log in the connection gets closed after a while (from 10 to 20 secs), sometimes I can't even connect to the machine.
I ran Wireshark on my Windows machine to try to figure out the issue. I don't know if the screenhot below can be of any help:
IP 192.168.9.10 is my laptop address on the OPNsense LAN. 192.168.3.100 is my physical PC IP.
AFAIK, I don't think that the problem has anything to do with OPNsense. I have the same problem if I run a Mikrotik x86 VM with pretty much the same network setup in Proxmox.
Could you help me figure it out please?
Thanks
