XG85 SSL VPN test internal with same network - join a drive to a directory on a joined drive error

Question

Hello, 
 I installed a new Sophos XG85 Firewall and configured the SSL VPN Remote configuration with this tutorial: https://community.sophos.com/kb/en-us/122769 
 Now I want to test a connection in the same local network as the XG85 is on. So im not on an external network. 
 I installed the Sophos SSL VPN Client from the user portal and the installaiton was successful. 
 When I try to connect with my user I got this message: 
 Thu May 31 12:01:14 2018 MANAGEMENT: >STATE:1527760874,TCP_CONNECT,,,,,, Thu May 31 12:01:24 2018 TCP: connect to [AF_INET]10.255.0.1:8443 failed, will try again in 5 seconds: Das System hat versucht, einem Verzeichnis, das sich auf einem mit JOIN zugeordneten Laufwerk befindet, ein Laufwerk mit SUBST zuzuordnen. 
 Does somebody know whats the problem?

But on the UTM it was possible from LAN. 
 Is it not possible when I activate the LAN zone for SSL VPN under Administration -> Device Acess -> Local Service ACL ?

Hi Patric, 
 The VPN connection from LAN will not work , it has to be connected to WAN interface from the external network.
