Firewall
In the presence of the firewall, anonymous Internet traffic is blocked. Using advanced
security features, you can redirect this traffic to a dedicated computer on your local
network Demilitarised Zone (DMZ) or open access from the Internet to the
iConnectAccess621 management ports (web, Telnet). The iConnectAccess621’s firewall
and NAT services (port forwarding, access control) can be disabled for all interfaces by
unchecking the
Enable Firewall
and
NAT Service
checkboxes.
Port Forwarding
Using the Port Forwarding page, you can provide local services (for example web
hosting) for people on the Internet, or play Internet games. When users send this type of
request to your network via the Internet, the iConnectAccess621 will forward those
requests to the appropriate computer. Port Forwarding can be used with DHCP-assigned
addresses but remember that a DHCP address is dynamic (not static). For example, if
you were configuring a Netmeeting server, you would want to assign this server a static
IP address so that the IP address is not reassigned. Also remember that if an Internet
user is trying to access an Internet application, they must use the WAN IP address. Port
forwarding will translate the WAN IP address into a LAN IP address.
Configuring Port Forwarding is a two-part process. Firstly you must ensure that you have
a LAN IP Address configured in LAN Clients, and once you have completed this, you can
then configure Port Forwarding.
