I left the INPUT and OUTPUT chains alone for now. Just want to get the FORWARD working. I created a rule to allow all RELATED traffic from each subnet to each other subnet. I then added a rule under FORWARD to allow tcp/8333 and tcp/8222 from ETH01 to ETH00. It seems to function ok. I am trying to figure out the logging part now so I can see if stuff is dropping/etc.
Thanks for the reply!
