WER-401 Wireless SOHO Firewall Gateway
(also called DMZ) to which all other incoming protocols are forwarded. To configure port forwarding to a
local server:
1. Enter a port number in an unused Service Port Range .
2. To forward only one port, enter it again in the Service Port Range after the “~”.
3. To specify a range of ports, enter the last port to be forwarded in this box.
4. Enter the IP address of the local server in the corresponding Server IP Address box.
5. Click Apply at the bottom of the menu.
Local Web and FTP Server Example
If a local computer, with a private address of 192.168.1.33, acts as a Web and FTP server, configure the Port
Forwarding menu to forward ports 80 (HTTP) and 21 (FTP) to local address 192.168.1.33 as shown in the
next table. In order for a remote user to access this server from the Internet, the remote user must know the IP
address that has been assigned by your ISP. If this address is 172.16.1.23, for example, an Internet user can
access your Web server by directing the browser to http://172.16.1.23. The assigned IP address can be found
in the Status Screen, where it is shown as the WAN IP Address.
Some considerations for this application are:
•
If your account’s IP address is assigned dynamically by your ISP, the IP address may change
periodically as the DHCP lease expires.
•
If the IP address of the local computer is assigned by DHCP, it may change when the computer is
rebooted. To avoid this, change the configuration of your computers to use fixed private addresses
rather than DHCP-assigned addresses.
Table 6-2 Port Table Entries (Example)
PORT # SERVER IP ADDRESS
Default 0.0.0.0
80 (HTTP) 192.168.1.33
21 (FTP) 192.168.1.33
Local computers must access the local server using the computers’ local LAN address (192.168.1.33 in this
example). Attempts by local computers to access the server using the external IP address (172.16.1.23 in this
example) will fail.
