Have just installed and configured 4-port wired router (Thompson SpeedTouch 510) for broadband sharing between 2 home PCs (one XP Pro, one 2000 Pro). Working fine, but: Only way I could get them to talk through the router, and get online, was to disable all firewalls. Was assured that routers have their own firewalls (seems logical), but when I checked security via my XP machine, Windows Update security check told me my XP firewall was not active. It can’t be if I’m going to be able to talk through the router; does the Update site only test the status of the built-in XP firewall, or does it mean I am open to intrusion? If the router does have its own firewall, how do I turn it on/configure it? Or is there a way of configuring the XP firewall to allow me to access the net and LAN? Please advise.
