By the way: host NICs routinely handle IPv4 IP and TCP/UDP checksumming. I suggest router vendors start adding the same logic to their hardware, and in a somewhat more general way so that IPv6 can also be supported, with additional headers between the IP and TCP/UDP headers when present. This will avoid similar issues in the future.
Done, circa 1998.
Must have been while you were away from Cisco, because the IOS _software_ that I tested a few years ago wasn't even smart enough to filter TCP or UDP with a fragment or AH header in between.
