Let’s see what options are available here. The Setup group comes first. These basic settings are divided into three subgroups: Internet, Wireless and Network. Choosing one subgroup you can then opt to set up the parameters manually or call for a Wizard’s assistance.
On the manual setup page of the first subgroup you can see a list of possible connections to the external network via the WAN port. You can then set up appropriate parameters depending on the selected variant. The DIR-655 supports six most popular connection variants: Static IP, Dynamic IP, PPTP, L2TP, PPPoE, and BigPond. The VPN-server access settings are exhaustive in the case of PPTP and L2TP: the situation when the server resides on a different subnet is supported.
The Wireless Settings page allows to choose the operation mode for the WLAN and to define connection security parameters. The connection channel can be specified explicitly or left for the router to choose. The security parameters comply with the requirements of the second version of the 802.11n draft (WPA2, AES).
The last page in the first group is called Network Settings. Here, you can choose the operation mode for the WAN port: router or bridge. (By the way, this is one of those settings that you expect to find somewhere else). Then, there are fields for entering the router’s internal IP address and the LAN mask. The parameters of the integrated DHCP server are listed below together with fields for reserving certain addresses, a list of reserved addresses and a list of IP-addresses currently assigned by the DHCP server.
