I just set up the Sophos UTM today. Everything is working great except for the Remote Access.
My UTM server is 192.168.2.100 on default ports for internal traffic and 192.168.1.250 for external traffic using two physical NIC cards.
My version is:
Current firmware version: 9.106-17
I followed the instructions as best I could in the "Remote Access via SSL Configuring UTM and Client" document. There appear to be slight differences from the Version 9.0 and the 9.106-17 that I am running but it wasn't hard to follow.
If I load https://192.168.2.100:4444 I get to the web admin just fine. The problem I'm having is when I attempt to load https://192.168.2.100 from any workstation to install the SSL VPN client. I get a generic error message from either Internet Explorer or Chrome on multiple desktops telling me it can't load the page. If I telnet to 192.168.2.100 on TCP port 443 it connects just fine. But I can't load that URL from any web browser.
I even forwarded port 443 in my main router to the 192.168.1.250 address, tethered my notebook to Verizon cell phone and attempt to access https://mypublicip and it received the same error as if I tried accessing the UTM server in this way locally. As such, I am unable to install the VPN client.
I enabled debug level logging and this is what is produced in the log when I load https://192.168.2.100
