Dont know how the 675 reacts, but as you are using classless IP addressing and subnet zero, it would be worth checking that you have:
ip subnet-zero ip classless Not sure on the 675 whether you would be stopped from entering the subnet zero address if this were not configured, and not sure whether this is IOS version dependant.
