I have a Win2K web server with 2 NICs. One for LAN and one
for WAN (No firewall device involved). I wanted to enable
TCP/IP filtering on the WAN NIC. So far I've set PORT
25,53,80,110 to be permitted in TCP and UDP and Permit All
in IP protocols. Some how my SMTP server is not working
anymore and Web browsing is not working either. The only
thing that works is the web site service. What did I do
wrong? Please help me out here.

Thank you in advance.
