Not unless you have a larger MTU on the "outside" interface than the "inside" interface, then you lose bigtime. I would check to see if this is the case in this situation, but those addresses don't come into my network so I can't. Offhand, I can't think of any other problems but I really discourage people from using internal address space for this purpose because it: - breaks stuff like path MTU discovery, etc. when filtered. - prevents easy identification of links, whose they are, etc. because you can't have reverse DNS and the addresses don't belong to you. - causes confusion when multiple networks that are using such addresses are merged or interconnected in the wrong (right) way. I like the idea behind why you would do it, but... can't justify it.
