I'd also be very interested in seeing how you configured your UTM to success connect to the ASA. I'm also trying to do this (as you know I've created a thread in the VPN section of this forum). The connection appears to be UP and established, but nothing can ping each other behind each endpoint. The WAN connection on the UTM side is handled by a cisco router (and managed externally). They've configured all traffic for the UTM's public IP to be sent to the UTM's LAN IP.
We can successfully connect using the Sophos VPN client on a laptop without a problem. Just the Site-to-Site is having the issue.
