Conection VPN between two sophos on AWS

We instaled two sophos utm on instaces in aws.
The instaces have a elastic ip, and we tried to conected each other by VPN IPSEC.
We add the elastic IP like a remote gateway but they can't conected.

  • 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.
