I am having trouble connecting to my PPTP VPN server.
setup is Cable Modem --> SPA2102 --> Switch --> VPN Server/other pc's
If I enable DMZ and allow all traffic through to the VPN server I can connect succesfully, however for obvious security reasons I do not want to expose this server to the internet.
Typically I would only enable port forwarding on TCP traffic destined to port 1723 to be passed through to the server.
Note SPA2102 Admin login is locked by VOIP provider, user login is available.
