I spent the weekend wracking my head trying to get a solid vpn connection to a new pptp server i'd setup. I could connect and get on the network but the connection would disconnect after 20 seconds. The server logs said the client initiated the disconnect.
So here are two non-obvious things I had to tweak to get a solid PPTP VPN through the DGL-4500
In Advanced > Firewall at the bottom under application gateway uncheck PPTP and L2TP
Second change was
In Advanced > Virtual Server setup a rule for IP 47 (which isn't an option) so what you do is
Click enable
Give the rule a name like IP47
IP Address, specify the computer you're going to VPN from
Protocol : set it to other, then to the left type in 47
Then click add
Of course also in this Virtual Server setup screen you'll setup a rule for PPTP as well which is straight forward, there's an option for it in the pull down.
Making these changes i've got a solid VPN tunnel at last.
