Re: [OOL] Network Setup Cisco DPQ-3925
said by Network Guy:
Does this setup imply that CV allowed this customer two authorized MAC addresses at a time? I don't see how the imac and the router would simultaneously work otherwise.
The router WAN interface still gets the public IP, as said above, like when the router is configured for Static IP, but the devices take a 10. IP instead of being configured for the static IP range - like if someone uses the Cisco 851 router and it loses the static IP config.
That DPQ3925 was never supposed to land on your residential, non-static-IP account. Tech must have confused it with a DPQ3912 - they are similar enough. Without static-IP, it's operating in NAT mode, and if you were operating another NAT box behind it, there's some significant caveats - NAT-behind-NAT doesn't work well for a few things (XBOX Live very much breaks, I think Netflix had problems with it, too). Fully explains why you were able to operate both a directly attached machine and a router at the same time, too - it has a 4-port switch, but all ports are in the same 192.168.x.x RFC1918 network.
