ipchains and cpanel5

I am using cpanel 5 and want to lock things down with ipchains/iptables and want to know what ports I MUST leave open.

Obviosly..

HTTP
HTTPS
SMTP
POP3
DNS
CPANEL WEB INTERFACE
FTP
SSH

Is there anything else I have to leave open for it to function properly?

Does anyone already have an ipchains config file (for use with cpanel) they could attatch?

Thanks.
