I am running a win2k3 server with Cold Fusion and SQL server sp3. I want to turn on TCP/IP filtering but dont know what ports i need open with regards to tcp/udp/ip.

I need the following items to work:

WEB (80)
FTP (21)
Terminal Server (1434)
DNS (??)
Remote desktop (3389)
SMTP (25)
SQL Server (??)
Cold Fusion (??)
What else am i missing?

Could anyone please help with determining which ports to open for each tcp/udp/ip? I tried but dns didnt work etc.

Thanks so much,

Pete

DNS (53) TCP/UDP
SQL Services (118) TCP/UDP

Cold Fusion I'm not familiar with. Sorry.

thanks but when i permit the following under tcp/udp:

80
21
25
1434
3389
53
118

i lose outbound internet cause it cant find the dns entries for domains. I can connect to ip addresses however. Also, eventhough i DONT PERMIT port 135, active ports shows that it is still listening. is that right?

THanks i really appreciate your help.

135 is RPC which windows requires. See the link below where you can download a spreadsheet that describes all the windows server specific ports.

thanks. one more question: i see an unauthorized IP connected to port 135 all the time (different ones) does this mean that my system has been comprimised? I ran a trojan scanner and it didnt find anything.

thanks,

Pete

I also loose internet when blocking UDP ports. I can get to internet if I use an IP
Can anyone tell me what UDP ports are needed for outgoing DNS resolution other than 53. I also need to know what ports for mail sevices too, POP3 etc...

Ports for various mail services:

SMTP Port 25 TCP/UDP
POP3 Port 110 TCP/UDP
