MikroTik

Hello,

I'm need to block all sites on guest network except 3 websites.
This network will be open (without password) but just can access to does websites.

Thank you.

PS: sorry my english.

Begin with http://wiki.mikrotik.com/wiki/Manual:IP/Proxy.

Specifically: http://wiki.mikrotik.com/wiki/Manual:IP ... ccess_List

Allow the three sites (it may be necessary to allow some sites on which those sites depend). Block everything else.

If they are your sites, you could use ip firewall filter rules to only allow access to those servers.

Make it apply only to your guest network.
