Interesting.   Does that allow other people to call you (first packets are 
inbound) as well as you calling other people (first packets are outbound)?

I guess the first few packets from them to you might get dropped because they 
don't match an "established" outbound connection, but as soon as you start 
sending packets to them, your firewall will allow two-way flow...

Have you done this using netfilter?
