Re: which tunnelling method to choose

Thats a pretty big question. But of all the ones listed in your question only ipsec incorporates Encryption.

GRE is just tunneling - you would need to implement encryption on top of that. i.e. 128 bit pptp.

L2TP is just tunneling as well - that is why Microsoft has l2tp/ipsec.

MPLS is also tunneling.
