I've just subtly renumbered my own home network to make sure the above 
condition is true...those hosts manually statically configured are now 
out of the 'statically allocated' dhcp and true dynamic DHCP ranges :-) 
Not that I got bitten by this feature 'cos everyone seems to use 
192.168.0/1....... and I don't :-)

Simon, is there any chance of a 'test5' bundling all the latest tweaks 
into a tarball?  It's much easier to get the LEDE guys to accept a test 
release tarball than it is loads of patches....and it means the code 
would get tested by a wider community.


Thanks,

Kevin
