Chapter 4 Tutorial
4.2.6Testing the Connections
1Open the web browser on one of the local computers and enter any web site’s URL in the address bar. If you can access the web site, your WAN 1 connection and NAT address mapping are configured successfully. If you cannot access it, make sure you entered the correct information in the WAN and NAT Address Mapping screens. Also check that the Internet account is active and the computer’s IP address is in the same subnet as the ZyWALL.
2Open your web browser and try accessing the web server (1.2.3.5) from the outside network. If you cannot access the web server, make sure the NAT address mapping rule is configured correctly and there is a firewall rule to allow HTTP traffic from the WAN to the web server.
3Try accessing the FTP server (1.2.3.4) from the outside network to send or retrieve a file. If you cannot access the FTP server, make sure the NAT port forwarding rule is active and there is a firewall rule to allow FTP traffic from the WAN to FTP server.
4.3 Using NAT with Multiple Game Players
If two users (behind the ZyWALL) want to connect to the same server to play online games at the same time, but the server does not allow more than one login from the same IP address, you can configure a
In this example, you have four static IP addresses (1.2.3.4 to 1.2.3.7) from your ISP. After you set up your WAN connection (see Section 4.2.2 on page 110), use the NAT > Address Mapping screen to map the third and forth public IP addresses to the mail server (192.168.1.12) and web server (192.168.1.13) respectively. The first and second public IP addresses are mapped to other outgoing LAN traffic. See Section 4.2.3 on page 113 for more information about IP address mapping.
When you finish configuration, the screen looks as shown.
