Sounds a lot like a IPFW on you FreeBSD box is allowing stateful
outbound traffic, but blocking incoming traffic.  What is the output of
the following command (run as root)?:

# ipfw list

What type of firewall do you have listed in your /etc/rc.conf file for
the variable "firewall_type"?  man "firewall" for more information.
