I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. Summary: document is ready for publication (with mild reservation). My thanks to the document editors for producing a readable document. Mild reservation: when I look at the use cases for PCP Proxy in this document (e.g. a consumer router doing NAT, connected to hotel NAT, connected to carrier NAT), it's hard to imagine that operational environment often fitting within the description of PCP's "simple threat model" (RFC6887, section 18.1). And once you reject the simplifying assumptions in that "simple threat model", RFC6877 says PCP needs a security mechanism (section 18.2 of RFC6877). Maybe this document should explicity reinforce that need, perhaps citing and blocking on draft-ietf-pcp-authentication?
