  So the packet is still not making it off of the machine?  That's
just... odd.  FreeRADIUS uses the normal socket calls to write packets.
 There's no reason for it to fail.

  The packet contents won't affect routing.

  DHCP doesn't interact well with routing rules.  It expects to send raw
packets out the interface, and to bypass IPv4 routing entirely.
