3.Click Add to save your settings.

The MAC address and IP address are displayed in the DHCP Client Lease Info table. The current system time is also displayed.

Remote Management

With remote management, you can allow a user or users on the Internet to configure, upgrade, and check the status of the gateway.

Note: Use very secure passwords if you enable remote management. Passwords should contain no dictionary words from any language, and should be a mixture of letters (both upper and lower case), numbers, and symbols. Your password can be up to 16 characters.

To manage this gateway through the Internet, you need its public IP Address, as seen from the Internet. This public IP address is allocated by your ISP. But if your ISP account uses a dynamic IP address, the address can change each time you connect to your ISP. There are two solutions to this problem:

•Have your ISP allocate you a fixed IP address.

•Use the DDNS (Dynamic DNS) feature so you can connect using a domain name, rather than an IP address.
