The session configuration settings for the SSL VPN service.
These settings are mergeable. Changes to these settings do not require a reboot of the system.
Field | Description |
---|---|
Session Mode |
Default = Always On.
This setting is greyed out and cannot be adjusted. |
Preferred Data Transport Protocol |
Default = UDP.
This is the protocol used by the SSL VPN service for data transport. For Release <%LISBON%> only TCP is supported. If you select UDP as the protocol when you configure the connection, UDP displays in this field but the SSL VPN service falls back to TCP. |
Heartbeat Interval |
Default = 30 seconds. Range = 1 to 600 seconds.
Enter the length of the interval between heartbeat messages, in seconds. The default value is 30 seconds. |
Heartbeat Retries |
Default = 4. Range = 1 to 10.
Enter the number of unacknowledged heartbeat messages that IP Office sends to AVG before determining that AVG is not responsive. When this number of consecutive heartbeat messages is reached and AVG has not acknowledged them, IP Office ends the connection. |
Keepalive Interval |
Default = 10 seconds. Range = 0 (Disabled) to 600 seconds.
Not used for TCP connections. Keepalive messages are sent over the UDP data transport channel to prevent sessions in network routers from timing out. |
Reconnection Interval on Failure |
Default = 60 seconds. Range = 1 to 600 seconds.
The interval the system waits attempting to re-establish a connection with the AVG. The interval begins when the SSL VPN tunnel is in-service and makes an unsuccessful attempt to connect with the AVG, or when the connection with the AVG is lost. The default is 60 seconds. |
