RDP server config for Clientless users

SriNarasimha005 — Sun, 07 Jun 2026 14:45:36 GMT

Hello Everyone,

We have a checkpoint firewall operating on R82 with mobile access VPN activated. It is set to 'application' mode.

In the native application -> endpoint applications, I am specifying the path for native RD (c:\windows\system32.mstsc.exe) where the mstsc application is installed on the endpoint machine and configuring the IP address in the parameter section.

When I click the link, I'm getting the login prompt to enter the creds tor Windows users. How are they able to log in to the destination server without the office mode IP address?

I'm neither using SNX to assign an IP address from office mode nor Apache guacamole server in this case.

Can someone please brief what's happening under the hood? Thank you.

I presume we are using some variant of the techniques that already exist to reverse tunnel RDP over various HTTP Reverse Proxies (which is what MAB is, effectively).

Hi @PhoneBoy

Thank you for your response. It appears to be functioning well on Windows.

Is there an equivalent solution available for MAC users without utilizing the Apache Guacamole server?

Presumably, the information necessary to achieve this is sent directly to the app in question (the Windows RDP app), either via the command line or an .rdp file.

You would have to create another Native Application that launches the macOS version of the Microsoft RDP app, which is called "Windows App" (used to be called Remote Desktop) and available from the App Store.
The path to the executable, when installed, appears to be: /Applications/Windows App.app
That advice is based on https://support.checkpoint.com/results/sk/sk105639 which suggests this is possible.

Hi @PhoneBoy

Thanks for the info. While we're trying to get this tested, I've come across below one.

sk104008 - Mobile Access Blade SNX (Native Application) Application Mode does not work with Mac OS X

Is this still valid? Any idea on this.

I suspect it is, given the date on the SK you found versus the one I found.
