Health Check – If disabled, the Alive Indicator Check is not performed. The default is enabled.
Health checking is performed by ICMP echo request and HTTP packets to the specified destination
that could be either: the Name or IP Address the user specified in the “Alive Indicator” input box
or
or the gateway of the WAN interface used if “Alive Indicator” input box is blank.
Alive Indicator – This is the IP address used to check if the WAN connection is operating. The
VPN800/8 F Firewall will contact this system to check if the WAN connection is working.
Change this address if you wish. Default is the gateway IP. Note: This is not used for PPPoE
connections.
MTU – The Maximum Transmission Unit determines the packet size to be used on the WAN
interface. Normally, this does not need to be changed, but if your ISP advises you to use a
specific MTU, enter it here.
