Conection VPN between two sophos on AWS

I am not all that familiar with elastic IPs, but I am guessing they act similar to dynamic ones until you release them.

The gateways would be your external facing IP addresses, or what I did was create a DNS host and used those after creating them on UTM.

Use the local RSA key to connect them, avoid the local pre-shared key word in my opinion - I have had nothing but problems with that, and it's not as secure as the RSA key generated by each UTM.

If you can, you could post some screenshots of your IPSec set up from the Remote Gateways tab and Connections tab so we can see the set up.  Feel free to obfuscate any IP address/other information you don't want public.

¡Hola! Enrique and welcome to the UTM Community!

In addition to the screen captures requested by Amodin,

     1. Confirm that Debug is not enabled.
     2. Disable the IPsec Connection.
     3. Start the IPsec Live Log and wait for it to begin to populate.
     4. Enable the IPsec Connection.
     5. Copy here about 60 lines from enabling through the error.
