Sophos Connect 1.3/1.4 no entry in local DNS

Question

Sophos Connect 1.4 ist working well and using our internal Windows DNS servers and can resolve our hosts correctly. But: 
 
 There is no DNS entry of the connected clients in our Windows DNS, so I can not ping the VPN clients from inside our LAN by their hostnames. Pinging the client's IP leased by Sophos XP works. 
 With SSL VPN Client that works. After a client connects by VPN, there is a DNS entry with hostname on our DNS server and I am able to ping the hostname from our LAN. 
 
 Does someone know how to solve this?

I have the same problem. The reason is probably that the Sophos Connect client create a network connection without "Register this connection in DNS" option selected and therefore Windows does not even try to register received VPN address on the domain DNS server. When I manually selected this option in the tcp connection advanced properties, everything worked fine. 
 
 Unfortunately, automating activation of this option is not easy. Microsoft does not provide any gpo policy for this. I only found this command in powershell: Set-DNSClient -InterfaceAlias 'VPN Name' -RegisterThisConnectionsAddress:$True but they should be started only after setting up the VPN connection. 
 But the best solution would be simply to improve the VPN client.

I just hope that the improved version of the client will also be available for the older version of Sophos XG Firewall 17.x, because as I have sadly learned recently, the new version 18 will not support devices of the Cyberoam iNG series .... :-( 
 Waiting for a new client, I found a solution. I created a new scheduled task that started with a 30s delay after detecting event 4004 in the Microsoft/Windows/NetworkProfile event log. His action is a one-line command with the following content: powershell Get-NetAdapter -InterfaceDescription "Sophos*" | Where-Object {$_.Status -eq 'Up'} | Set-DnsClient -RegisterThisConnectionsAddress:$True; Register-DNSClient
