Hi there,
I successfully managed to establish a GRE over IPSec connection following this article: https://kb.fortinet.com/kb/microsites/search.do?cmd=displayKC&docType=kc&externalId=FD40312
I have a Fortigate 100E and a CISCO 2901 router as connection endpoints.
I wuold like to test a connection with transport-mode set to tunnel-mode, but when I set this mode on both devices I get an error and the link do not go up.
Can you help me please?
Very kind regards.
Alessio
