For NordVPN user :
nordvpn whitelist add port 22 (THE PORT NUMBER OF THE PROBLEME APP / SERVICE)
and nordvpn whitelist add subnet 192.168.0.0/16
Here are the actual explanations for each command:
nordvpn whitelist add port 22 - Add a rule to whitelist a specified incoming port. You can also whitelist multiple ports — just separate their numbers with a space.
nordvpn whitelist remove port 22 - Remove the rule to whitelist a specified port.
nordvpn whitelist add subnet 192.168.0.0/16 - Add a rule to whitelist a specified subnet.
nordvpn whitelist remove subnet 192.168.0.0/16 - Remove the rule to whitelist a specified subnet.
IT SEEM WE CAN'T WL all the ports for a subnet (NOrd VPN Chat is awsome, always quick and fast)
NordVPN : "Hmm, I believe that it doesn't whitelist all the ports. But thank you for your suggestion, I will pass this on to our developer teams, and they'll take a look at the possibility of adding this in the future."*
What I WhiteListed
. THE WL is WL both TCP and UDP.. To buy myself piece as it is my local network, I WL ports 9100,427,515,631 and it is working well
