So my girlfriend has recently started her masters in Germany, and her internet provided to her flat is from the University. She wanted a VPN and AirVPN seemed to be the most flexible choice, so we started there. Right off the bat, it seemed that the network was blocking all VPN traffic (it was impossible to connect to VPN, or even authenticate credentials while on the university network, but tethered to my phone we could connect to the VPN with no problems). It turned out to be even worse than that: even VPN over SSH is resulting in timeout errors, which seems to imply that the network is specifically blocking connections to AirVPNs hosts, as opposed to just VPN traffic (though I'll be the first to admit I'm relatively new to this and might be misdiagnosing). It turns out that the University actually had her manually set up her network with a self-assigned IP address, gateway, and manually specified DNS servers. I'm sure that's somehow related, but all I could think to try was adding another DNS (which didn't appear to help, but it also seems that the host names are being correctly resolved anyway). Any ideas would be greatly appreciated, I'm rather baffled here.
