You may specify one Trusted User, which is a PC that will be exempt from blocking and

PC with a fixed IP address.
Block Services
Firewalls are used to regulate specific traffic passing through from one side of the firewall to the
other. You can restrict outbound (LAN to WAN) traffic to what outside resources you want local
users to be able to access. In addition to the kind of blocking of sites discussed above, you can
block services like Telnet or Instant Messenger.
By default, the FR114P regulates inbound and outbound traffic in these ways:
•
Inbound: Block all access from outside except responses to requests from the LAN side.
•
Outbound: Allow all access from the LAN side to the outside.
You may define exceptions to the default outbound settings by adding Block Services definitions
to the Outbound Services table. In this way, you can block or allow access based on the service or
application destination IP addresses, and time of day. You can also choose to log traffic that
matches or does not match what you have defined.
