I'm using the VPN Express app to setup PPTP and L2TP connections. It automatically sets the VPN profiles up successfully for me. When I try to connect, get error messages telling me that the server did not respond.

I'm fairly certain that the network I am using blocks VPN connections somehow. Is there any way I can use the 'Proxy' settings at the bottom of a VPN connection configuration window to avoid this? Can someone just briefly tell me what that's supposed to do? I'm guessing the main thing I need to do is use an alternate port, and with the Manual Proxy settings it appears I can do that. I just don't know what I should use for a server and authentication.

Have you determined if your network is simply blocking the common ports that PPTP/l2TP use? If so, you would simply set up your servers to listen on non-standard ports and configure your iPad to match. You might need to use a common port like 80 or see what ports are open first. If the network is actually sniffing packets and detecting your VPN - you'll need to do something like set up a ssh tunnel or find another network / get them to poke a hole in it by human engineering methods. – bmike Nov 15 '12 at 18:09
I'm just assuming that they're blocking the ports. Is there any way for me to check? Also, the VPN server is set up through that app, so I don't know if there's any way to change listening ports. – Mark Lyons Nov 15 '12 at 18:14
