Advanced Setup Section
The second group of settings is called Advanced Setup. These are main router and Ethernet switch setup options.
The WAN page of this group is where you set up your WAN connections. Each parameter is specified on its own page and the whole setup process is carried out sequentially, in steps.
After the changes have been saved, the new connection appears in the list on the first page.
On the LAN page you can change the router’s local IP address, specify the parameters of the integrated DHCP server, and enable/disable IGMP and UPnP protocols.
The NAT subgroup of the Advanced Setup group contains as many as four pages: Virtual Servers, Port Triggering, DMZ Host, and ALG.
On the first page from this list you can make a certain type of traffic go right to a definite server on the router’s internal network. On the second page you can specify ports that certain applications, located on both sides of the router, will be communicating through. On the third page you can specify the address of a machine on the local network that all incoming traffic will be directed to. And on the fourth page you can enable/disable the use of the Session Initiation Protocol. All lists of this subgroup can contain up to 32 fields.
