Cannot connect to Devolutions Gateway

Hi,

I'm checking out the PAM module in DVLS and I'd like to test it with Devolutions Gateway but I can't get it to work. Our goal is to install the gateway at several customers to maybe also remove the need for a VPN connection. We'd also like to keep LDAP/LDAPS closed over our VPN.

DVLS and the target servers are on a different network with a firewall in between (No VPN). DVLS to Target Server traffic is allowed over TCP7171 and TCP8181

This is my install







Configuration in DVLS:


I also tried with IP adres but that didn't work
DVLS can resolve the DNS name


Target Server is listening for connections + firewall on the server is disabled


Firewall between these machines is allowing connections:



When saving and running diagnostics, I get the following:





I can sort of connect to the target server from the DVLS server:


But it says no certificate is installed


If I install the service with 'Enable the Gateway web interface', test connection works but

• Auto-Detect other settings does not
• I don't want that web interface
• I don't want the service scanning ports

What am I doing wrong?

Best regards,
Thomas
