Tunnel Remote IP Address:
Set the peer IP address of the tunnel.
Remote Network IP Address
: Please set the subnet IP for remote network.
Remote Network Netmask
: Please set the Netmask for remote network.
Enable Keep-alive:
Normally, the tunnel interface is always up. Enable keep-alive to determine when
the tunnel interface is to be closed. The local router sends keep-alive packets to the peer router, if
keep-
alive response is not received from peer router within the allowed time (‘retry time’ multiply
‘interval’, based on default settings, the time interval can be 30 seconds), the local router will shut up
its tunnel interface.
Keep-alive Retry Times:
Set the keep-alive retry times, default is 3.
Keep-alive Interval:
Set the keep-alive Interval, unit in seconds. Default is 5 seconds.
