@lostlogan, your problem is maybe, that you ticked "keep settings", which is the reason for your mess. It is possible, that the failsafe port is the WAN port and not LAN, please double check this.
Do a clean reflash out of the failsafe to tidy that situation up
@Rene, great. Can you specify the problem with the diskspace? :)
