I'm using PuTTy to connect to a home server I set with LinuxMint 15, open-ssh, all the necessary stuff.
I can login just fine with my user using the private IP like "email@example.com".
Then I installed no-ip Dynamic Update Client because I have a dynamic IP and I try to login with it like so: "firstname.lastname@example.org", the client connects but when I input the password, the server just refuses it. It does the same if I try to login using the public IP instead of the host name.
My assumption is that using that host name what I'm really doing is to connect to the router, could that be? My internet provider has a network where there are a couple of Access Points and everyone connects to them using WiMax antennas / routers (NanoStation M5) thus sharing the same IP, so it's not a simple network where my router is doing the NAT. In fact, in my situation there is a NAT in the access point where the NanoStation connects and another NAT in my Comtrend router that creates the Wi-Fi access point to my house... I hope the explanation is somewhat understandable.
So, my question is: What should I do to fix the login issue so I can connect to my home server using a domain name?
