enable Nat Traversal
Parameters
value
This parameter is supported if you create an vpn attachment in single-tunnel mode. Specifies whether to enable NAT traversal. Valid values:
true (default): enables NAT traversal. After NAT traversal is enabled, the initiator does not check the UDP ports during IKE negotiations and can automatically discover NAT gateway devices along the vpn attachment tunnel.
false: disables NAT traversal.
