Hi,

Can anyone share an example of NAT-Traversal with IPsec transport mode ?

I have the following configuration working for normal traffic but not the
NATed one.

conn private-or-clear
auto=ondemand
type=transport
authby=rsasig
failureshunt=passthrough
negotiationshunt=passthrough
ikev2=insist
left=%defaultroute
leftcert={{ cert_name_pattern }}
leftid=%fromcert
leftrsasigkey=%cert
rightrsasigkey=%cert
rightid=%fromcert
right=%opportunisticgroup


BR,
Ahmed
