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.
