Are you using the correct IP address for Internet Connection Sharing. I mean, 192.168.0.1 for the gateway (which connects to the Internet) and 192.168.0.x (where x = 1 to 9) for the other?

The firewall must be well configurated too… Again, I can’t see the relationship between a LAN that is down (at least the ICS) and avast ::slight_smile:
