This implies a misconfiguration on Lancaster's iperf boxen. My instincts
suggest that the machines' firewalls are getting in the way, but I have
every port listed in the "local service" page for each machine open (to
tcp connections anyway). Is there another port range we should open to
receive tests? Or do we need to open ports to udp traffic too?
Cheers,
Matt
