First off, check that it is also true when using a device outside the LAN. Easiest would be to check with your phone with wifi off. You probably won't get to the login.
If you do then it's time to check firewall settings.
Yeah ur right, i was on my LAN and thats why it worked. I only assumed because I was accessing it via my WAN IP it was 'automatically' public.
Wait what?
Hairpin NAT/NAT Reflection can make the experience of visiting the WAN IP from the LAN a different one then if you do it from somewhere else. Or what is your what?
NAT loopback, if supported and enabled, may appear to bypass firewall rules.
Basically, traffic to your public (WAN) IP that comes from inside the network is not subject to the same level of security as outside traffic would be. The last part of the parent comment didn't quite make sense, though.
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?
Thanks!
Can you access your wan ip when you are somewhere else than on your own lan?
If not, then this is probably just that your router does firewalling and nat is such order that you can access admin interface from local network via wan address.
If yes, then router has some serious misconfiguration.
Yeah exactly what happened, i was on my lan thinking WAN IP meant it was public - it was not :P
Are you browsing from outside your local network?
No I wasnt.. just realised this, thats a great relief really. Was afraid it had been publicly available all this time.
Learn something new every day :)
It's worth checking from an external network anyway, but I'd be surprised if it was public facing.
Do you see that only when you're on the LAN or also when you're coming in from WAN?
Ah yeah you're right, i can only access this interface if I am on my LAN. Tried with hotspot now and it doesn't "load" - so thats good.
My opnSense box does the same thing. I'd rather get to it via internal IP like pfSense worked. (I assume I can make that happen somehow, but I haven't researched it yet.)
It is just a loopback interface you are seeing.
