Note that most VPN connections begin right behind the router, hence traversing a NAT becomes an issue. PPTP passthrough comes in to allow a VPN network to cross over the NAT with ease. NAT or PAT doesn’t work without ports. The standard ports for PPTP, L2TP, and IPSec are used, and on a normal consumer-level router (or for custom firmware such as DDWrt) all you have to do is enable VPN-Passthrough to allow PPTP, L2TP, and IPSec through NAT and the firewall.
PPTP uses TCP port 1723 to establish a connection. If you have a firewall active on your computer or if your ISP blocks port 1723 then you'll not be able to connect to our VPN service. Here is how to check if PPTP VPN port is open on your PC to be able to access our servers.
