4.3.6 Testing the Connections
1 Open 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 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 ZyXEL Device.
2 Open 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.
3 Try 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.
4.4 Using NAT with Multiple Game Players
If two users (behind the ZyXEL Device) 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 many-to-many rule instead of a
many-to-one rule.
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 4.3.2 on page 67), 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 4.3.3 on page 70 for more information about IP
address mapping.
