Stop IKE negotiation if no packet received for n seconds
The period of time in seconds after which the unit will stop the IKEv2 negotiation when no
response to a negotiation packet has been received.
Enable NAT-Traversal
Enables support for NAT Traversal within IKE/IPsec. When one end of an IPsec tunnel is
behind a NAT box, some form of NAT traversal may be required before the IPsec tunnel can
pass packets. Turning NAT Traversal on enables the IKE protocol to discover whether or not
one or both ends of a tunnel is behind a NAT box, and implements a standard NAT traversal
protocol if NAT is not being performed.
The version of NAT traversal supported is that described in the IETF draft ‘draft-ietf-ipsec-
nat-t-ike-03.txt’.
NAT traversal keep-alive interval n seconds
The interval in seconds in which the NAT Traversal keepalive packets are sent to a NAT
device in order to prevent NAT table entry from expiring.
RSA private key file
The name of a X.509 certificate file holding the router’s private part of the public/private
key pair used in certificate exchanges. See ‘X.509 Certificates’ in the ‘IPsec and VPNs’
section for further explanation.
