Of course, firestarter is just running iptables rules, and most firewalls
that I have seen are no good at recognizing rules that may have been
written _outside_ the tool - yet because they're just iptables rules, they
still catch all the errors if somebody else created the rule.

# sudo iptables -L

Should tell you what blocked it.  Finding out where the rule comes from
could be harder...
