Tim,
Actually the following statement prohibits ODR:
<snip>
The only routes it [3550] should have are those which are directly
connected.
</snip>
If you implement ODR, the 3550 will also have a default route pointing
towards R5, making this solution unacceptable.
End result: NAT! :o)

ODR wasn't explicitly forbidden, so I think that would be allowed IF IT
WORKS.
