You might want to check more carefully exactly what the failure mode
was.  I'm willing to bet that the router has been configured to assign
addresses inside a specific RFC 1918 /24, and will do Something Terrible
to spoofed packets in that range, but will figure you know what you're
doing and pass them if you source a packet from outside that /24.
