hey,
I change the settings for iptables below is the iptables entry
iptables -A PREROUTING -t nat -s 192.168.2.0/24 -i eth1 -p tcp --dport 80 -j

But still I am not able to access Internet from the 192.168.3.0/24 network.
Some of the logs of iptables connection ( /proc/net/ip_connectrack)
udp 17 27 src=192.168.2.83 dst=202.54.15.30 sport=32835 dport=53
packets=2 bytes=148 [UNREPLIED] src=202.54.15.30 dst=192.168.2.83 sport=53

Machines Configuration are below
Centos4.0
eth0: 192.168.1.125/24
eth1: 192.168.2.126/24
Debian:
eth0: 192.168.2.83/24 gateway: 192.168.2.126/24 (eth1 of Centos)
I am still not able to guess which transparent proxy is not working.
Any other pointers?
Thanks & Regards
