IPSec is normally enough, the only reason to use a GRE tunnel inside the IPSec tunnel, and therefore creating overhead which detracts from the size of the packets you can send, is to send multicast traffic over it. Multicast, so things like routing protocol updates, will not traverse an IPSec tunnel, so add a GRE tunnel and send the multicast traffic down it.

To add to what V_S asked.

What are your requirements? Why do you need a VPN?
