Block WAN Request By enabling the Block WAN Request feature, you can prevent your network from being “pinged,” or detected, by other Internet users. The Block WAN Request feature also reinforces your network security by hid- ing network ports. Both functions of the Block WAN Request feature make it more difficult for outside users to work their way into your network. The default is Enable.

IPSec Pass-ThroughThe Router supports IPSec Pass-Through. Internet Protocol Security (IPSec) is a suite of protocols used to implement secure exchange of packets at the IP layer, and it is one of the methods used to enable Virtual Private Networking (VPN) tunnels. IPSec is more secure than PPTP. The default is Enable.

PPTP Pass-ThroughThe Router supports PPTP Pass-Through. Point-to-Point Tunneling Protocol (PPTP) is one of the methods used to enable VPN tunnels. PPTP is less secure than IPSec. The default is Enable.

Remote Management This feature allows you to manage the Router from a remote location, via the Internet. To enable this feature, select Enable, and use the specified port (default is 8080) on your PC to remotely manage the Router. The default is Disable.

MTU MTU is the Maximum Transmission Unit. It specifies the largest pack- et size permitted for network transmission. To use this feature, select Enable, and enter the value desired. You should leave this value in the 572 to 1492 range. The default is Disable.
