I need to establish an IPSec VPN connection to an Astaro Security Gateway using the Shrew VPN Client or some other free client. I already tried many configurations (Astaro ASG und Shrew VPN :: network lab, https://community.sophos.com/products/unified-threat-management/astaroorg/f/58/t/53198) but I don't get it done.
Establishing the Connection via the Astaro Secure Client is no problem.
According to the Shrew VPN Trace, the IKE Key Exchange is not successful

Because of my paranoia i had to obfuscate the IPs [:)]
I am happy about every hint and tip.
THX a lot
