Just as a quick addendum the firewall file lives in /etc/sysconfig/ip(chains/tables), this is chains for 7.2 IIRC - at least on 7.2 Alpha.
The most basic format, if you're in a hurry, is: -A/-I* CHAINNAME** -P PROTOCOL -s SOURCEADDRESS -d DESTINATION PORT -j what-to-do*** -l**** (if you want) * ADD or INSERT or DELETE ** usually INPUT or OUTPUT *** DENY or ACCEPT or MASQ or REDIRECT or RETURN - 1st 2 probably **** log to /var/log/messages if packet matching the rule arrives so to add a rule to deny ssh connections from anywhere to 192.168.0.1 -A INPUT -P tcp -s 0/0 -d 192.168.0.1/255.255.255.255 22 -j DENY -l Kind of short - better to read man ipchains (or, really, to use iptables but......)
