I asked a question just a minute ago about how GRE is encapsulated. That might help with this one, but does using a GRE tunnel mean that you are using a VPN? I would think maybe yes and maybe no, and if not, it's because you have to use IPSec to be using a VPN. I would think so because it says there are 2 ways to use VPNs...through tunneling and through IPSec. This subject is very confusing for me. Thank you,
You ask the question:"does using a GRE tunnel mean that you are using a VPN?". And the answer is not necessarily.
In current usage GRE is frequently associated with VPN. But there are certainly implementations of GRE that are not associated with VPN (just as there are implementations of VPN that are not associated with GRE).
