Alternatively you can define the rule to allow only authenticated users to access specific

services. Any user that has a user account in WinRoute will be allowed to access the

Internet after authenticating to the firewall. Firewall administrators can easily monitor

which services and which pages are opened by each user (it is not possible to connect

anonymously).

Only authenticated users are allowed to connect to the Internet

For detailed description on user authentication, refer to chapter

description on this topic, refer to chapter

7.6

Internet.

Second rule will deny the other users to access this service.
