I figured out the problem. Posting it here in case someone else runs into similar issue. There were two problems:- The dhcp wasn't working because CONFIG_FILTER wasn't selected. The forwarding with static IP addr wasn't happening because I had turned of the iptables which was also doing the NAT'ing and setting the ip_forward to true (part of the script)! Now it works great:-) thanks, Tuns --- Linux Mailing List <linux_tb@yahoo.com> wrote: > Hi, > > I hope this is the appropriate mailing list for this > question.
