Advanced IKEv2 n parameters
Retransmit a frame if no response after n seconds
The amount of time in seconds that IKEv2 will wait for a response from the remote unit before
transmitting the negotiation frame.
Stop IKE negotiation after n retransmissions
The maximum number of times that IKEv2 will retransmit a negotiation frame as part of the
exchange before failing.
Stop IKE negotiation if no packet received for n seconds
The period of time, in seconds, after which the router will stop the IKE v2 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
on page 392 for further explanation.
