File lib/tun.c:

Line 788: 			return 0;
we're not happy with the old code making assumptions such as where the gateway IP address is within the subnet.  In your propsoed patch, we also make assumtions: That there's only one non-link-local address (for each IPv4 and IPv6).  It should be rather easy to iterate over all such addresses and add all of them to the blacklist, shouldn't it?  Basically if there are 10 local ip addresses configured in the pool, we should skip all 10.
