SoftEther VPN User Forum

hi i install on my windows 10 pc the softether vpn , my problem is the pcs in same network connects but if the pcs in different network of server not connected correctly i try to forward ports but it didn't work

Check https://clients.dh2i.com/NatTest/ on both server and client.
If any detects "symmetric NAT", NAT-T will not work for sure.
If both detect "permissive NAT", NAT-T may not work because there could be a port restricted NAT.

Since port forwarding also does not work for you, you have two options:
1. VPN Azure (free but slow)
2. your own SoftEther server on a VPS

ok thanks for reply if detect "permissive NAT" my NAT-T may not work because there could be a port restricted NAT there is a solution to this problem
