Get pmfirewall, or bastille Linux, and use those to configure your
firewall.
man ipchains, read the ipchains howto at Linuxdoc.org.
Come back with specific questions, if you have any.
(A simple firewall for a host with one nic: # is the root prompt, ; is a
comment)
;Set all policies to deny, now the machine is effectively off the
;network
#/sbin/ipchains -P input DENY
#sbin/ipchains -P forward DENY
#/sbin/ipchains -P output DENY
;This machine can accept connections only for www
#/sbin/ipchains -s 0/0 1024: -d <your_machine_ip> 80 -p tcp -j ACCEPT
;ICMP should be allowed, stopping it breaks too many things
#/sbin/ipchains -p icmp -j ACCEPT ;From any to any
;Deny everything else and log
#/sbin/ipchains -s 0/0 -d <your_machine_ip> -l -j DENY
