I am growing tired of trying to get the Untangle IPsec module to work with AWS tooling for site to site VPNs.
Since the Untangle IPsec module is based on strongSwan I'm ready to take a shot at deploying a strongSwan instance in my Virtual Private Cloud and having it tunnel to the Untangle IPsec module.
My Untangle is an edge device, it does not sit behind another firewall. While it utilizes a dynamically assigned IP address, that address does not seem to change often, and I realize that if it does I expect I will need to reconfigure things. I'm just going to need to live with that unless the whole thing can be made to work via DDNS.
At any rate, before I start tilting at windmills yet again, can someone either provide general guidance or point me in the direction of useful guidance for connecting Untangle's current IPsec to a strongSwan server?
