This the existing chain in my iptable.
How do i add/edit/delete a source/target destination???

I used : iptables -L to view this...

Chain blacklst (4 references)
target prot opt source destination
DROP all -- 209.11.168.128/25 anywhere
DROP all -- 69.89.74.24 anywhere
DROP all -- games1.vip.scd.yahoo.com anywhere
DROP all -- zone.com anywhere
DROP all -- www.emode.com anywhere
DROP all -- www.downelink.com anywhere
DROP all -- 66.102.15.101 anywhere
DROP all -- ev1s-207-44-136-114.ev1servers.net anywhere

Simple question...but it would be really nice to know how to do this..

Thanks....

Are you using a script to start the ruleset or just the /etc/init.d/iptables setup?

If you are using the RH setup, the saved rules are in /etc/sysconfig/iptables
