XP SP2 firewall and Networking

Hi,

This is my first post in this forum. And before I wrote it, I searched a lot at no avail, perhaps my key words were not good enough.

Few days ago, I upgraded the host PC from XP Home SP1 to SP2.
If the SP2 firewall of the host is on, the client PC, running XP Pro, couldn't then connect to Internet (waiting 192.168.0.1 to open!).
Next day, I noticed that I need to disable only the Windows firewall of the 'Network Bridge' in (Widows Firewall -> Advanced). Obviously, the taskbar keeps showing me the 'Windows Security Alerts' icon.

My question is:
What is (or are) the exception(s) I have to add (in 'Settings') to the 'Network Bridge' connection so that I can enable its firewall again without problem?

Thanks.

Any idea about the exceptions to be added in "Control Panel -> Windows Firewall -> Advanced -> 'Network Bridge 8' -> Settings" to let the client IP "192.168.0.xx" be seen by the host "192.168.0.1" ?
