Re: Blocking ports

Hi..

You can apply ACLs on your PIX to block specifed ports/service, if you want to stop MSN Messenger try the following:

In configuration mode on the PIX..

access-list inside deny tcp any any eq 1863

access-list inside deny ip any 64.4.13.0 255.255.255.0

Now apply the above access-list to the inside interface with of the PIX:

access-group inside in interface inside

Remember to clear PIX translations with commmand: clear xlate after the above modification and also save with command: write mem

Hope this helps and let me know if you need further help, please rate this post if it helps.

Jay.
