1. Go to Configuration> Network > Virtual Private Networking (VPN) > IPsec > IKE > IKE
Responder > Advanced.
2. Configure advanced IKEresponder parameters as needed:
Stop IKE negotiation if no packet received for n seconds
The period of time in seconds after which the router will stop the IKE 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 document draft-ietf-ipsec-nat-t-ike-03.txt.
