Your iptables setting is making the problem here. If you are using MASQUERADE with POSTROUTING chains on nat table you have to specify the --to-ports option. Set your ip-tables as, # POP Requests /sbin/iptables -t nat -A POSTROUTING -o eth1 -p tcp -dport smtp -s 192.168.0.0/24 -j MASQUERADE # SMTP Requests /sbin/iptables -t nat -A POSTROUTING -o eth1 -p tcp -dport 110 -s 192.168.0.0/24 -j MASQUERADE Check /etc/services file as, smtp 25/tcp # Simple Mail Transfer Protocol pop3 110/tcp pop-3 # Post Office Protocol - Version 3 See more here at, http://squid.visolve.com/squid/trans_caching.htm and iptables manpage (MASQUERADE part) > 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.
