Re: [Masque] Adoption call for "Requirements for a MASQUE Protocol to Proxy IP Traffic"

[Tommy Pauly <[e-mail]>]

Looking through the document, I believe that it is a good starting place for the milestone and ought to be adopted.

Like some of the others on this list, I personally have more interest in seeing the CONNECT-UDP work get solidified soon, but I think that IP proxying is an essential part of MASQUE, and good to keep discussing in parallel.

I’d like to the working group hash out of some of the requirements in detail—it seems like we’ll be reinventing a lot of the work of IKEv2 traffic selectors based on the current description. This can be complex, and we should avoid duplicating work where possible. I’m also curious if we see ways forward that allow IP proxying without some of that complexity. These can all be discussed after adoption, though.

Best,
Tommy
