TCP IP Filtering

[dvanbeek]

I've enabled TCP/IP Filtering on Windows 2003 R2 Standard Server.

TCP
21
22
23
25
53
80
110
143
220
443
445
465
995
1433
2006
3306
3389
5053
8306
8401
8402
8425
8443
8880
32000

UDP
53
1434

After applying this settings, it takes up to 30 seconds to locate any website on the server.
Also I can't navigate to any external website from the server.

I also can't resolve IP's based on domain names.
I've doublechecked that port 53 for DNS is open on TCP and UDP.

Kinda lost here
