asterisk users - Apr 2006 - asterisk at home, broadvoice and iptables

I can't seem to register properly with broadvoice servers. Looking at
tcpdump and log files I see registrations attemtps and traffic to
broadvoice, but no traffic or error messages of any kind from broadvoice.
Do my rules look ok ?
