I have a Redhat Linux AS 2.1 server working as proxy server. I have an ADSL line to connect to the internet, my server has 2 NIC, one connected to LAN, the other connected to ADSL modem. I have configured squid.conf file for all workstations connect to internet through my server. Everything is OK. But I also want all clients behind proxy can check mail POP3 with Outlook Express integrated in Windows and extra clients can use YM, webcam. I have known that POP3 and SMTP needed to open ports 110 and 25, but I have tried, not successfully.
Please instruct me to solve this problem.
and send me to email@example.com, thank in advance.
