If the tunnel request does not include an authentication group authentication will be based
on the client side Local Host ID in the tunnel request. The server side FortiGate unit
searches its peer list to match the client side Local Host ID in the tunnel request. If a
match is found, authentication is successful. If a match is not found authentication fails.
If the server side FortiGate unit successfully authenticates the tunnel request, the server
side FortiGate unit sends back a tunnel setup response message. This message includes
the server side Local Host ID and the authentication group that matches the one in the
tunnel request.
The client side FortiGate unit then performs the same authentication procedure as the
server side FortiGate unit did. If both sides succeed tunnel setup continues.
