ISC Bind, at least, has security problems that should be patched. I strongly recommend that you upgrade this system. > 3.

You don't need to forward UDP. Two: Port 20 is used for outbound connections from an active mode FTP server. You don't need to forward port 20 in to your server, ever. > 4.

They're not needed. I've never actually seen the Ping/ACCEPT syntax before, so I'm going to assume that entry is correct. It doesn't exist in Shorewall 4+. Your rules should contain only this (assuming you're actually running an XMPP server on your firewall): Ping/ACCEPT net fw ACCEPT:info all fw tcp 22 ACCEPT all fw tcp domain ACCEPT all fw udp domain ACCEPT all fw tcp 5222 DNAT net lan:192.168.1.231 tcp 21 DNAT net lan:192.168.1.231:22 tcp 2222
