Hmmm.... found a minor but really annoying bug in the IPSec code. The
fix is simple, but difficult to automate in bash.
Anyone have an easy to figure out which interface corresponds to a
particular network?
For instance, if I have the below, then for input "192.168.10.0/24",
then I want the output to be "br1".
Anyone know of an easy way to do this? I could do it with perl easily
enough, but that's not an option here...
Thanks,
