I currently have the eval VM of UTM 9 running under virtualbox. I would like to use the WAF (and OTP) to access a Remote Desktop Web Gateway.
I have setup UTM according to this document: https://sophserv.sophos.com/repo_kb/120454/file/Configuring%20UTM%20firewall%20for%20Remote%20Desktop.pdf.
However, when i access to UTM via the external interface i get no reply. I can see that the request is coming in, but no reply is send (using tcpdump on the external interface).
tcpdump on the internal interface shows one request per second (probably health check), but no extra requests when accessing from external.
The Live Log shows nothing.
Question is: Where to go from here? I have no experience with Sophos, so i do not know where to look now.
