Re: how to block teamviewer remote desktop

Since teamviewer seems to use outbound port 80 (http) for the communication channel, effectively blocking it will be somewhat complex. The best way I can think to accomplish this would be to define custom regex to match the identified traffic and then use a class-map to block it.

This Cisco article describes the process:

Hope this helps.

Re: how to block teamviewer remote desktop

many thanks for all your efforts,

i will try and show the result, meanwhile, some other software similiar to teamview, like logmeon, securelogin, Timbuktu Pro, can also protect from the above statements.

thanks in advance,
