Guest Services Policy page without Authentication broken on firmware SonicOS 7.3.2

Firewall configured with Guest Services -> Policy page without authentication page is broken post upgrading to 7.3.2. The guest users will be re-directed to "This page is redirecting. Click Here" message instead of "Terms of Use Agreement" configured in the Policy page without authentication section of the zone settings.

Symptom/Error would look something like this:

To temporarily fix the issue, the workaround is:

1. Navigate to Network | Interfaces and Edit the Interface on which Guest users reside/connecting from

2. Enable "Add rule to enable redirect from HTTP to HTTPS" but in order to enable this, should either enable "HTTPS management" or "HTTPS user login"

For demonstration I have shown X0 interface setting:

3. If HTTPS management cannot be enabled on this interface, you can instead enable “HTTPS user login.” This will automatically activate the setting “Add rule to redirect HTTP to HTTPS.” As a result, users and administrators will be prevented from logging in to the firewall on that interface, ensuring secure management access.

Hotfix & Resolution

• A hotfix is available starting with baseline firmware 7.3.2.
• The permanent fix will be included in the upcoming release till then if possible please use the workaround.
• Refer to Issue ID GEN7-58183 in the release notes of the next firmware for confirmation
