Authenticating external users to firewall like Sonicwall?

[SmartEdgeJC]

Hi all,

I am configuring a PA-500 for a POC exercise with a customer who is currently using a Sonicwall.

While there are obviously other/better ways to accomplish this and I realize how silly this is, given the limited scope I'm presently working in, I need to find a way to replicate a feature they presently "require".

In Sonicwall world, a user outside the corporate network can browse to the WAN IP of the firewall and log in with their credentials to become a "Trusted User" on the firewall.  A firewall rule applying only to "Trusted Users" then allows them to RDP to a different IP in their /28 which gets NAT-ed through to a Remote Desktop server on the inside.  Kind of a "Captive Portal in reverse", I guess.

Is there any way to replicate this functionality as closely as possible in PAN world??

Many thanks!

Hello Jeff,

You can set up and customize a captive portal to direct user authentication by way of an authentication profile, an authentication sequence, or a client certificate profile. Captive portal can be used in conjunction with the User-ID Agent to extend user identification functions beyond the Active Directory domain. Users are directed to the portal and authenticated, thereby creating a user-to-IP address mapping.

Also  If the user cannot be identified based on login information, an established session or client probe, the firewall can redirect any outbound HTTP requests and redirect the user to a web form. The web form can transparently authenticate the user through a NTLM challenge, which is automatically evaluated and answered by the web-browser or through an explicit login page.

If these users need connect from the outside/internet, enabling CP on WAN interface would be taxing for the firewall resources. Only alternative that I can think of is using Global Protect configured with External Gateway.

Users can connect to GP portal/gateway and authenticate using their AD/Radius/Kerberos/Local DB  credentials and would be assigned an IP from the configured IP pool.

Security policies can be configured between the tunnel zone and Inside zone to access the RDP server.

Plus....GP (1Portal + 1Gateway ) does not need licenses starting OS_4.1.x

HTH..!

Typing wan ip to a browser.....

users are outside on the internet ? or inside just guest....solution will depend on their position...

Captive Portal looks like a suitable solution for that.

Outside on the internet.
