Server firewall can't close AFP port 548

Running 10.4.9 (not Intel) my external IP address I have shut down everything in the firewall except pop3 and http toward this server (call it x.x.10.200) and yet when I do a port scan - AFP and Ping still show up as vunerable. I am running stealth on TCP and UDP and have all ICMP boxes unchecked.

anyone with some experience with this would be appreciated.

Also my bad: the somehow hitting a control return key combination while in Advanced Settings clears and kills all those settings. could I get a screen print or list of what was in there?

btw; I have put port 548 in the deny alway in under the advanced settings also and it still shows open to a port scan.

Thanks
