Softether VPN client gives error 1 unless DMZ or directly connected
Posted: Tue Oct 17, 2017 2:45 pm
Hello. I am having an issue with Softether VPN client giving error 1 when behind my SonicWall. If I bypass the firewall completely and connect the computer directly to the modem, Softether connects just fine and is fast and reliable. Same if I enable DMZ. But once I'm back safely behind my firewall, I get error 1 and no connection at all (unless I use VPN Azure which I don't like doing). What do I need to configure my firewall to allow in order to connect through it? It already allows ICMP. Thanks in advance.
