Description
router. With NAT-T enabled, IPSec traffic flows transparently through a NAT device,
thereby allowing one or more remote hosts located behind the NAT device to use
secure L2TP/IPSec tunnels to access the router. The ipsec option nat-t command
affects only IKE SAs negotiated on this virtual router after the command is issued; it
has no effect on previously negotiated IKE SAs. The no version disables NAT-T for
the current virtual router. The default version restores the default NAT-T setting,
enabled.
