I’ve a double NAT setup. Port forwarding is set up on both routers and it should work fine as the VPN server that is on the same machine that is running PMS is working fine.
PMS is currently picking up 200.x.x.x Pub IP while when I resolve my ddns name with $nslookup I get an IP 100.x.x.x.
I’ve tried putting the PMS machine directly to the main router and I have the same issue, so double NAT is not causing any problems as its properly configured.
