Outside interface listening on HTTPS "502 Bad Gateway"

L4 Transporter

I have this odd issue whereas one of HA Pairs seems to be listening on 443 on its outside interface for GP but I don't use GP and never had.  I have a interface profile that allows HTTPS but not from any IP and when I disable that it still shows that page.  no GP portal configured either.

 

How can I stop it from listening on 443 for any source IP?

There's a couple of thing that could cause the firewall to 'listen' on the external interface:

 

- don't enable a management profile on the external interface (even for valid remote admin, set one on the internal interface and apply NAT + security rules)

- is there an inbound rule with a url filtering profile/are response pages enabed on the external interface

- is there an inbound nat rule that's not set properly

- is there an authentication/captive portal rule active that may have been set too wide (any)

It was a lingering GP profile on Panorama pointing to one of the stack templates for this HA pair.  Once I removed it that message went away.  And FWIW if you have a management profile on an outisde interface and its locked down to source IPs then non-source IPs wont see that port open whereas they do with a GP profile.
