Router, under default configuration the firewall protection will not allow the access, then conflict occurs – at
the same time Router has to protect computers in LAN from WAN, at the other time it has to allow access of
valid users in WAN.
Here the Router provides you
“Internal Server” function to solve the conflict. Virtual Server provides one se-
rvice port. All service requests to this port will be relocated to the servers whose IP address has been appoin-
ted in LAN.
Function
After been setup the IP Router can allow some services, such as DNS � SMTP � POP3 � HTTP � NEWS � FTP � Telnet �
PPTP in LAN, to be open to Internet. Then users from Internet can access servers in your LAN; Or by setting up
DMZ Server you can allow all application services and ports of one Server in your LAN to be open to Internet.
Setup Method
1. Please confirm the LAN services which you wan to be open to Internet according to the following list:
Protocol Server
DNS DNS (Domain Name Server) DNS (Domain Name Server)
SMTP SMTP (Simple Message Transfer Protocol) SMTP (Simple Message Transfer Protocol)
POP3 POP3(Post Office Protocol) POP3(Post Office Protocol)
HTTP Web Server
News News Server
FTP FTP File Transfer Server
Telnet Telnet Server
PPTP VPN (Virtual Private Network) VPN (Virtual Private Network)
2. Choose the Server which you want to be open to Internet, then input Server IP address. Click “Apply ““ ” but-
ton to make current setup valid. Note: All open protocol port should be standard port, otherwise Router can
not transfer the data package from the invalid port which you have configured; You can change external port
number. But other users who want to access the services which you have setup have to setup the port number
before successful access.
3. If you want to setup
“DMZ Host” please choose “DMZ ” option, then input the internal Server’s IP address
which you want to be open to Internet. Router will transfer all received data packages except those which have
been setup in
“Internal Server” to DMZ Server, and will allow the unlimited dual communication between
DMZ Server and outside Internet. If you are using a new network application but Router can not transfer data
package without knowing the Port of this application, then you can setup all DMZ ports to be open. After DMZ
service being effective, firewall protection of this computer will be invalid, please notice the safety.
