I have a new, very basic route-based vpn failing to setup on my SRX P1 with this message:
Exchange type mismatch (configured 4, proposed by peer 2) for tunnel local:<my ip> remote:<remote ip> IKEv1
My end is an SRX, the remote end is a Fortigate 300D supposedly.
Any idea precisely what is misconfigured on their end (what does not match my IKE config?
My guess was they are proposing aggressive mode to my main, but that's merely a guess and they say not. Possibly they're proposing IKEv2? I am just not familiar enought with Fortinet stuff to lead them.
I have looked all over to see precisely what "4" and "2" are in the exchange type as if there is a key, but I have not found anything on the Juniper site.
