UTM login prompt when using a NATted IP

We have an internal website that we only allow employees to access. We have a NAT policy that only allows a few source IPs to access the server. If anyone on the list connects using the NATted IP, the UTM properly passes the traffic to our internal server where users log in.

The difficulty we're having is when a user NOT in the list attempts to connect, they are getting a login prompt from the UTM portal. This is creating confusion.

Is this normal? How can i change it, so when users not on the list try to connect, it just times out.

  • Steve, you might want to change the port on the 'Advanced' tab of 'User Portal' - I like to use 2443.

    If you have a Webserver Protection subscription, you might want to use that instead of the DNAT.

    Another possibility would be to replace the DNAT with SSL VPN Remote Access.

    Cheers - Bob
