i m using ISA 2000 Server,how can i block certain ports ,and allow some ports like 5005,5002 etc

[Yogeeraj_1]

hi,

below an example on how i once configured my server to block outbound traffic on known MyDoom ports:

1. In ISA Management, expand Servers and Arrays, , Policy Elements.

2. Right-click Protocol Definitions, point to New, and then click Definition.

3. Type MyDoom (, ) in the Protocol Definition Name dialog box and then click Next.

4. Type in the Port Number dialog box.

5. Select in the Protocol Type drop-down list.

6. Select Outbound from the Direction dialog box.

7. Click Next.

8. Select No from the Do you want to use secondary connections? option, and then click Next.

9. Click Finish.

Note: Because MyDoom used a contiguous range of ports, these steps 2-8 had to be repeated for each port in the range.


hope this helps!

kind regards
yogeeraj

Hello KFA,

in ISA 2000 there are a wizard tool to configure the rules.

Right click on the right panel, on the server and select "New rule" (if i don't wrong, the name are this)
