I am able to browse the net from the gateway machine. 2) check the ip_forward by doing cat /proc/sys/net/ipv4/ip_forward Answer : It is permanently set to 1 3) the masquerade rule for iptables is something like this For say network 192.168.0.0/24 /sbin/iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -d 0/0 -j MASQUERADE (also assuming ur using iptables and the 2.4 kernel) Answer : Yes I am using Red Hat 9 and I am using above mentioned rule except "-s 192.168.0.0/24" I shall modify the rule and check again. 4) Some ISP's dont allow ICMP packets so check whether you can access the network using some other protocols. Answer : I am not sure about this I shall check with the ISP. 5) Forget DNS for now, try accessing some sites by IP, a good check would be to see if you can do a "whois" or a "dig", If you can ping an IP address, try pinging your DNS server to see if they are they are up to perform name resolution, maybe that isnt set correctly. Answer : I shall try that ... thanks. The main reason to use NAT instead of Squid (squid-2.5.STABLE4) for proxy is the same mentioned by this gentleman : http://www.squid-cache.org/mail-archive/squid-users/200208/0102.html SOS .... Can anybody guide me on this if possible .... Hope this helps... Regards, Keith "joel_divekar" wrote: > Hi All > > I an trying to share internet access using NAT.
