My housemate and I have networked our computers. However, if he hasn't turned off his firewall, I cannot access the internet. How do we get around this without him getting paranoid about his computer being more suseptable to hackers, viruses etc... thanks
How have you networked your PCs ?
Did you configure ICS on the PC connected to the Internet ?
What Firewall are you using ?
If you are using ICS and ZoneALarm then:
Under the "Firewall" option in the program window, click the "Advanced" button. A smaller window named "Advanced Settings" will come up.
Under the "Internet Connection Sharing" section, choose the option "This computer is an ICS/NAT gateway".
That's all. You can leave your Trusted Zone setting on "Medium". Never tried it on "High", though.
