There are security implications with that. If you are thinking "my wireless
already does crypto, I don't need ipsec" then you're wrong.
It is also not recommend to use ESP with the NULL cipher, and I would
not recommend running AH instead of ESP either, but that will also get
you authentication without encryption (auth=ah)
