For IPsec, yes, if you're using AES or 3DES, it will offload that from
the CPU.  For PPTP, no.  It doesn't use AES or 3DES, so that won't
help any there.  If you have a lot more IPsec than PPTP, it would be a
good solution.  If it's mostly PPTP, you'll need to upgrade to a 4801
or WRAP or something faster.
