[Cialug] IPTables Concept

[Jerry Heiselman]

You need two rules.  One allowing the setup of the connection on port
22 and one allowing established connections to continue.  I am not
sure about the syntax in iptables, but I would imagine it might look
something like:

ipfw -p INPUT -dport 22 -flags setup -j ALLOW
ipfw -p INPUT -dport 22 -flags established -j ALLOW
ipfw -p OUTPUT -flags established -j ALLOW

Warning: Untested, probably not even valid syntax.  Just to give you an idea.
