Use this command to generate periodic traffic on one or two VPN tunnels.
The ping generator generates traffic in an IPSec VPN tunnel to keep the tunnel
connection open at times when no traffic is being generated inside the tunnel. For
example, the ping generator is useful in scenarios where a dialup client or dynamic
DNS peer connects from an IP address that changes periodically—traffic may be
suspended while the IP address changes. You may also use the ping generator to
trouble-shoot network connectivity inside a VPN tunnel.
You can configure settings to generate ping commands through two tunnels
simultaneously. The ping interval is fixed at 40 seconds.
The source and destination IP addresses refer to the source and destination
addresses of IP packets that are to be transported through the VPN. When a
destination address of 0.0.0.0 is entered for the ping generator, the address means
"none".
