I have enabled TCP/IP Filtering feature of Windows 2000. I did following setting:
1. Permit all UDP Traffic
2. Permit all IP Traffic
3. Permit TCP Traffic on port 80, 20, 21, 25, 110, 53, 443
With this setup, everything works nicely except FTP. The customers are unable to ftp to their accounts. The can ftp to port 21 but when ftp client connect to random data port after login then the socket error pops-up which is obviously because that random port number is a disallowed ftp port.
My qeustions is, how do I configure tcp/ip filtering to allow FTP also.
