Thanks for the suggestion.  I'm fairly sure that in the cases of DES, 3DES,
MD5 and SHA1, the keylength is fixed.  In any case, when I tried this,
racoon failed while parsing the configuration complaining that a key length
was not allowed.

It looks like the AH key length needs to be forced to 128 bits???


"For algorithms that can take variable-length keys, algorithm names can be
followed by a key length, like blowfish 448."

Have you tried something along the lines of '3des 128' ?

Just a guess.
