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.
