SSL VPN: Need to set client IP address

Hi all,

Using UTM 9 (v9.705-3) here. I recently finished setting up SSL VPN for Mac users (newer versions of macOS and iOS had issues connecting to L2TP/IPSec), and am experiencing a little issue.

When a user connects, they are not able to establish a remote desktop connection. Our workstations use the 255.255.240.0 subnet. 

When using the L2TP/IPSec connection method, I am able to specify an IP address ("RAS Address") for each user that needed it. Is there a way to do this for SSL VPN?

    No, not possible for the SSL VPN.

    I suspect that your internal devices have active firewalls that block IPs outside your local subnet - disabling the firewall on a test machine would confirm that.

    If you don't want to disable firewalls on internal devices, you could simply SNAT RDP traffic from "Internal (Address)."

    If you search here, you will find the modification needed to let L2TP/IPsec work with the newer versions of Apple OS.

    Cheers - Bob
