It seems you are unable to send UDP packets to the VPN server. Can you run it under strace or truss or whatever the Darwin equivalent is, and work out what's happening? Can you send UDP with netcat to the server? A packet dump might enlighten. Maybe we *do* send a single packet, get an ICMP unreachable, and then the OS gives you a failure when you try to send the *next* packet? Either way, it shouldn't be fatal; you should have a working connection over TCP. It's just not as efficient as it should be, and will suffer badly if you experience packet loss. -- dwmw2 -------------- next part -------------- A non-text attachment was scrubbed...
