(SOLVED) Is it normal that browsing to my own WAN-IP shows my Omada controller interface? (slrpnk.net)

Hi there, been working on my selfhosted setup a bit lately and just noticed that if I browse to my own WAN-IP it will show to the public the interfance of my oc200 omada hardware controller. While it does have a login form with username password, id be much more confident if this wasnt public at all. I've looked online and in my settings but struggle to find anything related to this. Is it common that this is on be default?

Any pointers greatly appriciated.

Edit: Solved - I panicked without thinking I was on my own lan when checking this..

I know you solved it but for anyone that finds this later this feature/behavior is typically called “NAT Hairpin” in case you are looking for a setting to enable or disable, hope this helps!

In pfSense land it's called nat reflection. I believe it's off by default on pfSense, but it makes accessing your own stuff "externally" while inside the network a pain so I'd imagine most devices have it enabled by default.

Yeah, I've never fixed this issue with my fritz.box, only thing that helps is calling up my DynDNS URL. Is there a better way?
