Configuring Client Services
Enabling Special Applications
Some applications require multiple connections, such as Internet gaming,
videoconferencing, Internet telephony and others. These applications may not work when
Network Address Translation (NAT) is enabled.
Specify the port normally associated with an application in the Trigger Port field, select
the protocol type as TCP or UDP, then enter the public ports associated with the trigger port
to open them for inbound traffic.
Virtual DMZ Host
If you have a client PC that cannot run an Internet application properly from behind the
NAT firewall, or after configuring the Special Applications function, you can open the
client up to unrestricted two-way Internet access.
Remote Management
By default, management access is only available to users on your local network. You can
manage the RoamAbout R1 from a remote host by adding the IP address of an administrator
in the Remote Management page.
Client Filtering
You can filter Internet access for local clients based on IP address, application type (i.e.,
HTTP port), and time of day.
If an application still cannot function correctly after enabling multiple
ports, you may have to open the client PC for full Internet access using the
DMZ Host option.
Adding a client to the DMZ (Demilitarized Zone) may expose your local
network to a variety of security risks. Only use this option as a last resort.
• If you specify an IP address of 0.0.0.0, any host in your local network can
manage the RoamAbout R1.
• Only one management session can be logged in at a time. You must log out
of the current session on the system before you can manage the
RoamAbout R1 from a different system.
