Dear Sirs, As mentioned in the 'NAT-HOWTO' I've done the following to configure my Linux box as masquerading gateway for internal network : #iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE and #echo 1 > /proc/sys/net/ipv4/ip_forward The problem is I can ping or telnet a remote host from an internal network but browsers say 'unknown host' when I try to load a remote site. Please help me with this problem. Regards Rajesh _______________________________ Do you Yahoo!? Express yourself with Y! Messenger! Free. Download now. http://messenger.yahoo.com
