RE: IPSec over GRE why ?

["Shelton, Raymond A." <SheltonR@health.missouri.edu>]

I wasn't that person, but let's pretend I play him on T.V. for a moment...
imagine that I have a GRE tunnel to a remote clinic; further suppose I need the traffic to be IPSec b/c of HIPPA regs.  Should I have more accurately asked for IPSec in GRE, as opposed to GRE w/in IPSec?

Why don't you ask the person who told you to use GRE?
