### Describe your issue
On diag page, yunohost say than ports aren’t exposed.
On my router, I’ve manually opened all ports listed in Yunohost’s firewall page (because UPnP was too easy right ? Why disable this and let the option…mystery).
What I have to do in addition ?

You need to forward the ports to YunoHost as well or setup YunoHost as DMZ on the router, which will forward everything to YunoHost.

I don’t realy understand what the point with DMZ… For me, a DMZ is an isolated sub part of local network, why this will open all port ?

I’ve set my Yunohost as DMZ, but nothing change on diag page.
Also my IP has change so I run `yunohost dyndns update --force` but this time nothing happen, I’va always the error :

Today DNS error is ok (I make no change but it’s ok…)
So only ports aren’t opened despite DMZ and NAT.

Did you check for your router guides? Some routers require some more configuration to allow open ports. And check your Internet provider allows you to open these ports

My internet provider is Orange (Sosh) and by the past I was able to open ports.
My 5g router is a netgear Nighthawk M6 and I’ve open ports (see screenshot shared bellow in previous post).
