I have configured IPsec Tunnel between FortiGate and RUTM51, and the Tunnel is UP and connected, but the probleme i am not able to ping between both sites, the configuration from the Fortigate site i am sure that is okay, but i am not sure with the RUTM configuration.
i created a new lan 172.18.0.0/24 on the Port 3/4 and i trying to ping from this subnet to my remote site 10.0.0.0/8. but nothing work.
Could you confirm if you are still facing issues with your IPsec setup between FortiGate and RUTM51? If so, would it be possible to provide any logs from the FortiGate tunnel side or RUTM51?
