Can you explain the mac and arp -a command? Would that show a different IP address other than what is showing up on the Network screen in windows? Also, for the firmware, I've tried several versions but none seem to work except the ES version which still doesn't allow me to access the web interface. I've read there could be a firewall in these preventing USA access, were these only sold in the UK and that is why they work for some users and not others?
Seriously, this should not be that hard but I think something is blocking them. I bought 5 brand new in package on eBay not knowing they were special for Sage etc. I've been setting up IP cameras for 15 years doing the port forwarding and the whole 9 yards. This is a new hurdle for me.
