postgresql

This is probably as basic as it gets but I'm a developer and really have no experience with iptbles.

The only connections I need opened are:

eth0 (outward facing)

ssh
ping
SSL to tomcat (forward port 443 to 8443)

eth1(local subnet)

connection to postgres server

Everything else should be blocked. My current attempts seem to be leaving all other ports open. I wonder what gives.

Thanks serverfault!
