Today I had accomplished Queue tree configuration. it was great.
But I need something more from Mikrotik Router Operating System.
How can i Block the Connection to Messenger Service such as MSN Messenger, Yahoo Messenger and other Messenger services.
I need it bcoz in my company, there is a rule not to allow some of the employee not allow to use those Messenger Service.
It make the working performance down..
I manage to solve the problem by look up for those services IP addresses.
And block any outbound connection from those employee computer.
But it just temporary solution, bcoz those messenger services grow fast enough, it use other IP addresses and sometime change those IP's to new one.
Can I use Mikrotik to check any outbound connection from the messenger services hostname?
In Example for that, I had manage pull up complete list of MSN messenger services IP addresses and hostnames.
Such as this :
* Dns resolved 207.46.0.11 to baym-dp1.msgr.hotmail.com
* Dns resolved 207.46.0.12 to baym-dp2.msgr.hotmail.com
...
* Dns resolved 207.46.0.95 to baym-cs351.msgr.hotmail.com
* Dns resolved 207.46.0.96 to baym-cs352.msgr.hotmail.com
...
MSN Messenger services use the almost the similar hostname,
like "baym" ; "msgr"; and "hotmail.com"
Can I make a criteria for connection using those matching hostname?
for example :
If a new connection destination match to "baym*.msgr.hotmail.com" string, it will automatically rejected.
Sometime the company also want the network staff to block some website also, such as game website http://www.thecrims.com
Can I make a criteria for those website from the HTTP Header for outgoing website connection to that web?
By filter the HTTP Header using the destination website match with "*thecrims*.com" string?
In Kerio software, it can be done.
The software can filter the outgoing connection by matching the string that we want to filter using wildcard string.
Anyone have any suggestion?
Using script or something?
Or Mikrotik does not implement filtering outgoing connection by destination hostname?
