I use AirVPN as a VPN through my openVPN Client on my Tomato Router. MY problem is, I cannot get access the cloud connect service (A DDNS service provided by ASUSTOR my NAS manufacturer) once connected to the VPN I cannot activate it within the NAS settings, the error being no UPNP/NAT-PMP support within the router. That's why I thought there was a port or something not open to allow this service to run through the VPN. I opened UDP port 1900 and TCP port 2869 on the VPN which are the UPNP ports and still no difference, however, I later learned that you cannot open ports lower than 2048. The 1900 port is showing as RED
I have complete the DNAT command successfully within Tomato with other ports and I get the GREEN lights not problem. This is really frustrating me as I need the UPnP/NAT-PMP service to access my NAS externally e.g. on the another internet connection.
Has anyone else had this problem if so how did you fix it?
I'm willing to try anything.
