Hi,

What operating system are you using?  Linux/Solaris/MacOS/Windows?

If Linux and especially RedHat9, you will need to enable ip_forwarding. In /etc/sysctl.conf adjust:

   # Controls IP packet forwarding
   net.ipv4.ip_forward = 1

The POSTROUTING and PREROUTING are disabled if net.ipv4.ip_forward is 0.

Hi,

Sorry for asking a well known question. My squid configuration seems to be fine. but 
the outlook express at client machine is not working.

My configuration:

eth0: 192.168.1.97 (My Public IP)
eth1: 192.168.5.1 (My Lan IP)

I have declared 25 and 110 as the safe ports also but still :((

Based on therad i saw at linux solve, I tried to do

/sbin/iptables -t nat -A POSTROUTING -o eth1 -s 192.168.0.0/24 -j MASQUERADE

But this also having no effect.

plz guide me to make my pop3 and smtp connections as transparent.

I am attaching my squid.conf file with the mail.

regards,
Anuradha
