I've got an OpenVPN server set up and it works wonderfully, with all internet traffic using the VPN connection. On one specific WiFi network, I can use telnet/openssl s_client to connect to web servers, but not in the browser. I really want to stress that this is not the typical "no internet with OpenVPN" question, but it's unique to one single network. Is there a good place to start looking to resolve this? Thanks for any advice, and here's relevant information:
