We sorted the problem with the crossover cable, a new cable fixed it. The old one was damaged but I didn't think that was likely, in my experience a cable either works or it doesn't, there's no middle.
Anyhow, we have a new problem. My girlfriend can't log in to Live Messenger or Hotmail from her computer anymore when connecting to the Internet through my Mac that runs Internet Sharing.
We have tried disabling all firewalls and any software that might be in the way but nothing seems to work. The connection troubleshooter in Messenger sometimes reports Key Ports to be blocked and sometimes reports them as open, regardless of whether any firewall is running, and either way she can't log in. Speaking of which, Microsoft doesn't seem to want to tell us what ports Live Messenger uses... but I looked around the net and found some info and also read the firewall log and opened the ones that it attempted to use.
Do you have any ideas? Has anyone had this problem?
