The compression algorithm to use with this IPsec tunnel. The options are:
No (None)
DEFLATE
Delete SAs when this tunnel is down
When selected, all SAs associated with the IPsec tunnel are deleted when the tunnel goes
out of service.
Delete SAs when router is not a VRRP master
When selected, at least one Ethernet interface must be set as VRRP Master before the
router can create SAs. If the router switches away from VRRP Master state, the SAs will be
deleted. When the router switches back to VRRP Master state, the SAs will be created
automatically.
Go out of service if automatic establishment fails
The router will take the IPsec tunnel out of service if the automatic establishment fails
rather than continually retrying.
Go out of service after n consecutive auto-negotiation failures
The router will take the IPsec tunnel out of service if the auto-negotiation fails for the
specified consecutive number of times rather than continually retrying.
This tunnel can only use apn
When enabled, this parameter allows you to choose between using the main APN or the
backup APN, as defined in the Configuration – Network > Serial > W-WAN Port page.
Link tunnel with interface with x,y
When enabled, this parameter can be set so that the IPsec tunnel will only match packets
using the specified interface. When this parameter is enabled, the route will take outgoing
packets going through this IPsec tunnel and recheck to see if the resultant packet also goes
through a tunnel.
If the inner tunnel is an IPsec tunnel (i.e. needs IKE), you can get the inner IKE to use the
correct source address (matching the outer tunnel selectors) by enabling the Use
secondary IP address parameter and the inner IKE will use the IP address configured in
the Secondary IP address parameter on the Configuration – Network > Advanced
Network Settings page.
Inhibit this IPsec tunnel when IPsec tunnels n are up
This is a list of IPsec tunnels that can inhibit this IPsec tunnel from being used as long as
they are up. If this IPsec tunnel has been allowed to come up, and the IPsec tunnel that
inhibits it comes back up, this IPsec is taken down and any SAs that may have existed are
removed. As soon as an inhibiting IPsec tunnel goes down, the router will check to see if the
inhibited IPsec tunnel can now create SAs.
Inhibit this IPsec tunnel unless IPsec tunnel n is up
This IPsec tunnel will be inhibited unless specified IPsec tunnel is also up.
