Hello all, I am new at iptables and am tring to learn for furture projects. For an expirement I tried this. "iptables -t nat -A POSTROUTING -s 172.16.12.131 -o eth0 -j SNAT --to 172.16.12.167" This is all on a 172.16.12.x subnet. from the same machine I then tried to ping 172.16.12.200 and I got nowhere. When I deleted the rule it worked fine. Could someone tell me were I went wrong and or maybe point me in the right direction. Thanks Dominic Iadicicco __________________________________ Do you Yahoo!? Yahoo! Mail is new and improved - Check it out! http://promotions.yahoo.com/new_mail
