Hi Raj, 1. As far as I understand, only one data channel can be created within one IKE SA. So, if application needs several different channels, it have to create several separate IKE SAs, performing authentication several times (probably involving human activity, if EAP is used).

That's true. I don't see any requirements in section 10.4. that the probes must be distinct. Request/reply nature of IKE's messages make them well suitable for probes and I see no need here to introduce separate mechanism, adding complexity, consuming bandwith and adding delay. Moreover, sectio

As a note to the WG, I asked Raj to turn in a revised draft which covered some of the points that Valery and others have made. Given the number of questions asked so far, I would prefer that the WG hold off on discussing this draft until there is a new, clarified draft. --Paul Hoffman _

Hi I think one of the most striking things is how similar all three mechanisms are. They all begin with a node doing what the DMVPN guys call a "hairpin" - it decrypts packets from one peer, then re-encrypts them and sends them to another peer. In all three proposals, the node doing the hairpi

Hi all, first, I think that the draft is very important for interoperability. But I also think, that in its current form it is insufficient in some situations and could have been made better. The problem, that the draft is not solving, is the situation, when one of the peers has more than one pr
