I have serveral VMs that need UPNP router, to function properly. Is there any way to setup proxmox networking to be able to do UPNP and have it in bridge mode so VMs get privat IP # and than access net via one nework device. Currently I've setup VMs in bridge mode, so they get direc public IP from ISP, but ISP will only let me use 2 public IPs, and I need min 3-4 VMs working via UPNP all using same apps on the same port.
