I have enabled TCP/IP Filtering on my Windows server 2003 to block the inbound traffic, I have enabled following ports in TCP/IP Filtering and Enabled TCP/IP Filtering
TCP ports: 20, 21, 25, 53, 80, 110, 143, 443, 807, 808, 1433, 3389, 5357, 8004, 8010 and 8011
UDP ports: 6514, 6515 and 6516
These ports I require.
One Strange Thing is happening that Now I am not able to resolve any DNS Name like google.com.
If I disable the TCP/IP Filtering then I can easily resolve the domain name google.com
Any one can help me in this matter. Server is on Remote location so I can't use any firewall software. I require to enable only TCP/IP Filtering.
