I have generated several ssl certs/openvpn config files for the autistici vpn server (info at vpn.autistici.org). Every time I try to run the config file with openvpn, it seems to connect, and gives me the "initialization sequence completed" message. But when I open my browser and try to open a page, it only gets as far as "looking up example.org" and won't load any further. Suggestions?
