For anyone who don’t know what’s Sophos UTM is, its a very nice Firewall Appliance (it’s free for homeuse) . It’s a Unified Threat Management Gateway. With Webserverprotection (SNI Support), reverseproxy and so much more! U can run it on a dedicated hardware or as a virtual machine
For peoples who know sophos utm -> I have started a feature request here http://feature.astaro.com/forums/17359-utm-formerly-asg-feature-requests/suggestions/10409280-let-s-encrypt-integration
Vote for it, so that they hopefully integrate the letsencrypt client completly.
best regards
