I have:
Windows 7 Ultimate desktop PC with internet through cabled router
Windows 8.1 Home laptop PC with internet through mobile Android WIFI

I find out my public IP and ping it to confirm (check)
I configure my router to forward various ports (check?)

I then have the following 3 things found - example values used:
With IPConfig I know my local IP address is "1.2.3.4".
My local computer is called "nameexample" in the LAN workgroup.

...

In Windows 7 Control Panel\Network and Internet\Network Connections
I choose "File | New Incoming Connection"

In this dialog I created another account(?)
called "vpnuser" with password "vpnpass".

After having done so, Windows reports success and tells me I will
need the computer name information which it shows, i.e. "namexample".
I am not actually sure if I actually need this or not anywhere.

I then try connect from Windows 8 - but this with error
"800" where it states the tunnel was unreachable.

...

I then go back and see I in Win7 and Win8 can edit
properties and e.g. choose encryption/handshake type.

And there is also something called predefined key...
But that is slightly confusing since I have not had
the opportunity to configure a preshared key.

The current situation is hat I have not been able
to get any VPN configuration I havet tried working.

Can anyone suggest a guide I can use? One that tells:
* what to forward in router
* what to enable in Windows Firewall
* what settings to use (defaults appear not to be working)

I would prefer a setting that is reasonable secure
(L2TP? But what protocols/handshake can I allow on it?)

...

Do you think it could be a problem my Laptop is
connected to the internet through a mobile phone?
Could that be the cause somehow?

A hotel could be even worse many times they limit the ports allowed or run your through a proxy server. A proxy will block all types of VPN except sslvpn because they can't tell it is not a HTTPS session.

You never really know. This is why I tend to always use sslvpn it seems to be the simplest to get to work. The only down side of sslvpn is when you are using it in TCP mode on a very high latency connection it will run a little slower than something like pptp or ipsec.

I have had massive issue trying to get vpn to work though mobile broadband. You have at least 2 NAT translations if not more. The devices have to have special support to allow ipsec running in natt mode though.

SSLVPN tends to work better but you will have to load a server since it is not part of windows. OPENVPN is sorta a sslvpn and works ok as long as nobody is activly trying to prevent a VPN since openvpn does not 100% follow the ssl rules and can be detected.

I must ad mit I had problems with OpenVPN finding out how I could actually make it accept VPN connections. I could see OpenVPN was used by various 3rd party solutions that provided client configuration files, but... well, the GUI had nothing about configuring anything for incoming connections. Anyhow, this was after not too much Googling, so I could possibly solve this with some more research :)

However, I had *really* hoped I could get the built-in Windows thing working. What should I do above to get the Windows incoming connection part correctly configured? I will then try take my laptop to a friend's house who also have cabled internet connection.

However, one more question. What if I am at a hotel with a WIFI? Will I have the same VPN problems with as when I try use the mobile phone WIFI?

You are a fool who does not even read the threads. Are you getting paid to advertise this site that will get you a ban. Where did he ask for a vpn service he is setting up his own vpn back to his house.

So anyone who find this thread in the future is advised NOT to visit the above linked site because it is likely a scam.
