Hi,

I have a Cisco 2600 Router, is there anyway of stopping the use of msn messenger through the hardware?

 
If you block these addresses in an access list - 65.54.183.198 65.54.179.198 - MSN will not work. Alternatively you can block traffic on port 569
 
You can use access list to deny the trafic to msn messenger.
Use netstat -n commnad to find out which port MSN messenger works. You can block that port or that IP address.
 
Hi,

Bit of a novice when it comes to router configuration, but when I wish to stop a client pc accessing the outside world i use the command:

deny ip host 152.232.x.x any

What command would i use to block a specific client ip address from access the port that msn messenger uses?

Any help will be gratefully received.
 
I'm guessing ur using standard access lists. You need an extended access list to block a certain port/protocol.

http://www.cisco.com/univercd/cc/td/doc/product/l3sw/4908g_l3/ios_12/10w518e/config/acl_cnfg.htm
tells you all about how to configure access lists.

Make an extended access list: (the number 110 can be anything between 100 and 900 I beleive-not sure about 900 though, standard lists number till 99)

access-list 110 deny ip 152.232.x.x 0.0.0.0 any any eq 569

then put the access list on a port. the "eq 569" specifies the port. I could be a bit off on this (been a while) but I'm 100% sure you have to look up on how to configure extended ACL's
