This is done by mapping virtual servers to private IP addressed, according to the specific TCP port
application. As the planning table below shows, we have identified a Telnet (port23) virtual server for
private IP 192.168.15.56, a SMTP Mail (Port 25) virtual server for private IP 192.168.15.33, and Web
(port 80) virtual server for private IP 192.168.15.64. For example, all Internet requests to the gateway
for SMTP Mail services (port25) to the WAN IP address will redirected to the Private Network computer
specified by the server IP 192.168.15.33.
Service Port Server IP
23 192.168.15.56
25 192.168.15.33
80 192.168.15.64
It is Recommend that IP address of virtual server computer hosted on the Private Network be manually
(statically) assigned to coincide with a static server mapping to that specific IP address. Virtual servers
should not rely on the dynamic IP assignment of the DHCP server function which could create
unmapped IP address assignments.
Protocol – Selection of UDP, TCP, or Both (TCP and UDP) allows these specified network protocols to
pass through during the TCP port communication with each virtual server IP address.
10.5 DMZ
Click the entry on the left hand
navigation panel for Firewall – DMZ.
The Demilitarize Zone (DMA) host
allows one computer on the Private
Network to be to tall expose to the
wired network or Internet for
unrestricted two-way communication.
This configuration is typically used when a computer is operation proprietary client software or 2-way
communication such as video-teleconferencing, where multiple TCP port assignments are required for
communication. To assign a PC the DMA host status, fill in the Private IP address which is identified as
the exposed host and click the Apply button. However, any Internet user who knows the WAN IP
address of the gateway can connect to the DMZ host since the firewall feature is disabled for this
device, causing a potential security risk to data residing on the that host.
Again, it is recommended that IP addressed of DMA host computers on the Private Network be
manually (statically) assigned to coincide with a static DMZ host mapping to that specific IP address.
DMZ hosts should not rely on the dynamic IP assignment of DHCP server function which could create
incorrectly mapped IP address assignments to non-DMZ hosts.
10.6 Advanced
As advanced firewall functions, you can enable/disable
y Block Ping to WAN
y Web-based management from WAN port
y SNMP management from WAN port
