Hi there,

Since there seems to be a bit of confusion about blocking MSN I'll post my rules
here. They are very effective, but do NOT block the Web Messenger. You'll have to
add extra rules for that. (I've got a proxy for that....)

Add a rule to reject the following on LAN interface.

|------------------------------------------------|
|Proto|Src|Port| Destination     |Port| Desc.    |
|------------------------------------------------|
| TCP | * | *  | 207.46.110.0/25 | *  | MSNBLOCK |
|------------------------------------------------|
| TCP | * | *  | 207.46.104.20   | *  | MSNBLOCK |
|------------------------------------------------|

Since the block is effective, I've been called many thing.
These many things are not positive and I will not repeat them here.
Sorry for the folks at my work, but this is company policy...

Webmessenger should be blocked with this rule:

|------------------------------------------------|
|Proto|Src|Port| Destination     |Port| Desc.    |
|------------------------------------------------|
| TCP | * | *  | 65.54.239.22    | *  | MSNBLOCK |
|------------------------------------------------|

Good luck.
