Good morning ;-)
I am not block all outgoing traffic from the local box just the dns-requests coming from the box itself - I have bind8 running on the machine.
All other blocking-rules are in the forward chain ... so if I run win ther won't be a connection established all 3 min. :-) ... default policy (from the linux-box) for outgoing connections is allow (accept) ...
