Advanced WAN and LAN Configuration

To edit or eliminate a port assignment entry:

1.

Click the button next to that port in the table. 

2.

Click Delete or Edit. 

3.

Click Apply. 

If a local PC with a private IP address of 192.168.0.33 acts as a Web and FTP server, configure the 
Ports menu to forward HTTP (port 80) and FTP (port 21) to local address 192.168.0.33 

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 Maintenance Status Menu, 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. In this case, you can also consider using a dynamic 
DNS service provider which enables your FVS318 to use a Fully Qualified Domain Name as 
its Internet address. Dynamic DNS services allow remote users to find your network using a 
domain name when your IP address is not permanently assigned. 

•

If the IP address of the local PC is assigned by DHCP, it may change when the PC is rebooted. 
To avoid this, use the Reserved IP address feature in the LAN IP menu to keep the PC’s IP 
address constant.

•

Local PCs must access the local server using the PCs’ local LAN address (192.168.0.33 in this 
example). Attempts by local PCs to access the server using the external IP address 
(172.16.1.23 in this example) will fail.
