I want to report what I believe is a bug with ZoneAlarm firewall (latest free version) running under Windows 2000 SP4 (with all security updates) with my Buffalo G54 wireless adapter.
When my machine first boots, the wireless adapter has no IP address.
ZoneAlarm reports that its IP address is
After I connect, it
assumes the static address of (I'm not using DHCP here at my home office) and
ZoneAlarm still reports
its address is
ZoneAlarm then blocked all packets because it thinks they have been routed through my computer (see report below).
In order to access the internet, I have to shut down ZoneAlarm while my wireless adapter is connected, then restart it.
Here's a detailed log report on one blocked packet:
