Reference Guide for the Model RP114 Web Safe Router
Advanced Configuration of the Router 5-7
Use the PORTSmenu to configure the router to forward incoming protocols to IP addresses on
yourlocal network based on the port number. In addition to servers for specific protocols, you can
also specify a Default (also called DMZ) Server to which all oth er incoming protocols are
forwarded.To configure port forwarding to a local server:
1. Enter a port numberin an unused Start Port box.
2. Toforward only one port, enter it again in the End Port box. To specify a range of ports, enter
the lastport to be forwarded in the End Port box.
3. Enter the IP addressof the local server in the corresponding Server IP Address box.
4. Click Applyat the bottom of the menu.
Local Web and FTPServer Example
If a local PC, with a privateaddress of 192.168.0.33, acts as a Web and FTP server,configure the
PORTSmenu to forward ports 80 (HTTP) and 21 (FTP)to local address 192.168.0.33 as shown in
Table 5 -4.
Inorder for a remote user to access this server from the Internet, the remote user must know theIP
addressthat has been assigned by your ISP. If this address is 172.16.1.23,for example, an Internet
user canaccess your Web server by directing the browser to http://172.16.1.23.The assigned IP
addresscan be found in the MaintenanceStatus Menu, where it is shown as the WAN IP Address.
Some considerationsfor this application are:
• If youraccount’s IP address is assigned dynamically by your ISP,the IP address may change
periodicallyas the DHCP lease expires.
• Ifthe IP address of the local PC is assigned by DHCP, it may changewhen the PC is rebooted.
Toavoid this, change the configuration of your PCs to use fixed privateaddresses rather than
DHCP-assignedaddresses.
