Requiring Authentication To Connect To The Internet - D-Link DFL-500 User Manual

For example, if a policy denies connections to a subnet, you can add a policy that accepts connections
from one of the computers on the subnet. Policies that accept connections in this way must be added to
the policy list above the connections that they are exceptions to.
•
Delete the default policy and then add policies to accept only the connections that you want the firewall to
accept
In this way you can limit Internet access to that allowed in the policies that you create. You must delete
the default policy because if it remains in the policy list, all connections that do not match another policy
will be accepted by the default policy.

Requiring authentication to connect to the Internet

When running the DFL-500 in NAT mode, you can configure policies to require users on the internal network
to enter a user name and password to access the Internet. To require authentication you must add users to
the firewall configuration, see
You can add policies to require user authentication for connections:
•
From addresses on your internal network (see
•
To addresses on the Internet (see
•
Using certain services (see Services)
•
During a one-time or recurring schedule (see Schedules)
Since policy matching works on a first-match principle, you must add authentication policies above the default
policy. You must also add authentication policies above matching policies that accept or deny connections.
