Only if the MTUs on all interfaces of the routers are the same. Otherwise you might generate a ICMP size exceeded message that will never reach the sender, breaking Path MTU Discovery.
And now I finally have something to add to this brilliant discussion. That is what I truly love about NAT. It breaks totally inane filth like path mtu discovery. I'm sure if someone had an MTU < ethernet on an internal router they wouldn't need NAT breaking path MTU discovery to bring it to their attention. -- Brandin Claar Network Analyst Penn State Applied Research Lab
