Smile CentOS - Internet access

Hello everyone,

I have a linux server running on CentOS, my network users are all Windows XP.

I want to block access to certain IP from accessing the internet.

Please let me know the procedure and also how to edit the access list.

edit ipchains

well i use fedora which is the same backbone as centOs so you have to edit ipchains like so.

ipchains -P forward DENY
ipchains -A forward -s\
This will accecpt ip forwarding for all PCs accept for the named address.
