The best thing to do, is to ensure your devices are listening to the correct ports. If you need any more help, just ask.
Thanks, but I do not think that was it.. I think there is a much larger problem. It happened again, this time I was able to get access to the router log and my IP-address went from the normal to an internal one 192.168.100.10
I'm still confused as wtf is going on... But for now I will continue as I am and just take note of what happened.
