Looking for some info on a way to block out hotmail with a Cisco 678 DSL Router. Can this be done? If so, how would I go about doing it? If not, how could I?

Additional info:

I have a Win2k Pro serving up files on a mac/pc network. The DSL dishes out ip's with DHCP. (i.e. 10.0.0.1).

DSL > Etherfast 24port Switch < server/comps

You should be able to set an access control list on the cisco router to block certain sites. You will have to reference your cisco documentation to see how to do this.

Alternativly you could use third party url blocking software. There are plenty of packages around - one i have used before is Surfwatch

First of all it's very easy, all you need is a sniffer from there you can find out what ports and what subnets to block, here I already did the research here is what you need to do:

using a outbound filter on your ether0 interface

block port TCP 1863 outbound and block 64.4.13.0/24 subnet as well.
just remember on a Cisco router you have to put in a permit any any on the last line so the rest of the traffic will flow, other wise everything will stop working..

iptables -p TCP -s 10.1.1.1 --dport 1863 -j DROP
iptables -s 10.1.1.1 -d 64.4.13.0/24 -j DROP

permit any any

As a matter of curiosity, why do you want to
block HOTMAIL, I as well as a great many
other people including users of this forum
use HOTMAIL as our primary mail address.
