After this question an internet connection to Windows 7 ought to be able to be shared to an Asus Router using Internet Connection Sharing. So I go into LAN3 and setup internet sharing with the Ethernet connected to the Router:
The connection appears to share but when I look at the properties for Ethernet and LAN3 the Ethernet shows No Internet Access.
There is no access for other PC connected to the (wireless) Router. What can I do to fix this?
PS It's not the Windows Firewall I have tried turning off Firewall and the same issue: no internet via the Router.
