I run a web server on one of my fixed IPs. 

If I connect my laptop firefox can get pages from the server using 
it's *external* address. However, if I use a WIFI connection for the 
laptop it can't. I can ping it though. Nothing I could see in the 
firewall log - and I log all drops.

Firefox "remembers" loads of TCP settings that other apps seem to re 
acquire. I had not expected a problem as I was switching from a wired 
connection to a wifi one provided by an ASUS WL-330ge - which is also 
ethernet connected to the laptop so the IP address and the mac address
presented to the outside had not changed. Firefox decifed he knew 
better.
