Billion BIPAC-741 GE V2.0 ADSL Firewall Router
37
Being a natural Internet firewall, this network router protects your network from being accessed
by outside users. When it needs to allow outside users to access internal servers, e.g. Web server,
FTP server, E-mail server or News server, this modem can act as a virtual server. You can set up
a local server with specific a port number that stands for the service, e.g. Web (80), FTP (21),
Telnet (23), SMTP (25), POP3 (110), When an incoming access request to the router for a
specified port is received, it will be forwarded to the corresponding internal server.
For example, if you set the Service Port number 80 (Web) to be mapped to the IP Address
192.168.1.2, then all the http requests from outside users will be forwarded to the local server
with IP address of 192.168.1.2. If the port is not listed as a predefined application, you need to
add it manually.
DMZ: The DMZ Host is a local computer exposed to the Internet. Therefore, an incoming
packet will be checked by the Firewall and NAT algorithms, then passed to the DMZ host when
a packet is not sent by a hacker and not limited by the virtual server list.
If you have disabled the NAT option in the WAN-ISP section, this Virtual Server
function will hence be invalid.
If the DHCP server option is enabled, you have to be very careful in assigning the
IP addresses of the virtual servers in order to avoid conflicts. The easy way is that
the IP address assigned to each virtual server should not fall into the range of IP
addresses that are to be issued by the DHCP server. You can configure the virtual
server IP address manually, but it is still in the same subnet with the router.
