In my office we connected to a lan which is dont have internet connection for the last few days. but i connected to another wireless connection through wlan adapter to my server. the two default gateways are 192.168.1. (LAN) 192.168.0.1 (WAN). when i tried to share the wan connection to lan, i get an error. Internet connection sharing cannot enabled. A lan is already configured with an ip address that is required for automatic ip adressing. (my lan connection is configured by static ip)
The problem is exactly as reported. ICS needs the 192.168.0.x network to configure the connection needing access to the Internet. But that's already in use by the connection w/ the Internet access. You'll have to reconfigure ICS to use something other than the 192.168.0.x network.
