said by michaeljc70 :What does "share the public IP" do exactly?
I tried that, but the Internet IP on my router looked the same (internal IP, not real IP).
Did you reboot? Are you sure you have things set up correctly?
When I select "Yes, use public IP address" next to "Let LAN device share Internet address?", my router info looks like this:
IP Address :108.88.XXX.XXX ( same as the IP assigned to my modem
Subnet Mask :255.255.252.0
Default Gateway :108.88.XXX.X
Primary DNS Server :68.94.156.1
Secondary DNS Server :8.8.8.8
