The following changes were made

* Removed non POSIX redirects
  * Removed setting of loopback up (seems to do this on its own?)
  * Corrected $verbose variable check (was -z, should be -n)
  * Added quotes for ip route command around $iface (colon was a problem)
  * Should note that v1.2 was incorrectly set in Makefile previously
