3Com WBR-6000 Network Router User Manual


 
If an application still cannot function correctly, try
using the "DMZ" feature.
DMZ
This feature, if enabled, allows the DMZ computer on your LAN to be
exposed to all users on the Internet.
The "DMZ" PC will receive all "Unknown" connections and data.
This feature is normally used with applications which do not
usually work when behind a Firewall.
The DMZ PC is effectively outside the Firewall, making it more
vulnerable to attacks. For this reason, you should only enable
the DMZ feature when required.
If Enabled, you must select the PC to be used as the "DMZ" PC.
Select the desired option
Disabled - DMZ is disabled.
Enabled- The selected PC is a standard PC on your LAN, but it
will receive any "unknown" connections and data, as described
above.
Multi-DMZ
This feature is only available if your ISP has allocated you multiple
Internet IP addresses.
If you have multiple Internet IP addresses, you can assign one DMZ
PC for each Internet IP address.
The "DMZ PC" will receive all "Unknown" connections and data
received for the Internet IP address associated with it.
All outgoing traffic from the DMZ PC will be assigned the WAN
IP address associated with it, rather than the shared IP address
on the WAN port. Note that ONLY the DMZ PC will use the WAN
(Internet) IP address you enter on this screen.
