It looks like it should work. Is it possible that the isInNet doesn't
work well with at "255.255.255.255" mask. You could try
if (myIpAdress() == "10.7.1.216") instead. I've never used it with host
masks, just subnets.

Also define "breaks down". Do those three host go through the proxy but
the 10.7.0.0 ppl go out direct or do you get some sort of error?

Finally I've had issues where myIpAddress() returns the first IP listed
by ipconfig on Windows 2k laptops that were VPN instead of the PPTP IP.
  Never did find a workaround.
