Select Enable VPN/Disable VPN. Click to manually enable/disable the device's VPN service.
Enable/Disable VPN Clients
(Available on VPN servers only)
The VPN server sends a 'VPN enable service' or 'VPN disable service' command to all of its clients when the user clicks the
Enable- or Disable- VPN Clients button.
Note: The command is broadcast a few times using the 'Network Latency' VPN setting as the delay (in seconds) between
each broadcast. Clicking this button again before the command-transmit sequence is completed will result in an error
message.
Warning: VPN clients cannot process commands from the VPN server while a user is accessing the VPN configuration
settings.
4.5.3.3 STATUS AND STATISTICS
― Number of Tunnels. VPN statistics are displayed for all tunnels. This value represents the total number of active
tunnels terminating in the unit. The maximum number of key-exchanging tunnels is currently limited to 128 on a VPN
server and 1 on a VPN client. A "Shared" tunnel is included in this statistic. It is used for special types of traffic such as
broadcast and multicast packets. The tunnel is always keyed, so the minimum Number of Tunnels shown is 1 when VPN
is enabled on the device.
― Tunnels Ready. Indicates the number of tunnels that are accepting traffic. Tunnels that are not ready block all traffic
passing through them.
― Tunnels in Key Exchange. Indicates the number of tunnels in key exchange. A key-exchanging tunnel is considered to
be "Not Ready".
― Packets Sent. Number of packets sent across all tunnels.
― Packets Received. Number of packets received across all tunnels
― Packets Received in Error. Number of packets received in error by the device from all VPN tunnels, possible causes
include:
* Reception of non-VPN packets when 'Block non-VPN packets' is enabled.
* Decryption errors due to network congestion, or packet corruption.Figure 56 – VPN Configuration
