Re: [pcp] draft-ietf-pcp-proxy-01

Hi Med,

Comments

[1] Section 3 PCP Server Discovery and Provisioning : 
You may also want to add details that PCP Proxy would use similar mechanism just like PCP client to discover the PCP server.

[2] Section 5 Control of the Firewall : 
Firewall rules would be typically to block any unsolicited traffic from outside to inside. For PCP request/response this will not be a problem, but would have issues with unsolicited ANNOUNCE. In this case PCP Authentication looks mandatory to handle man-in-middle attacks trying to act as PCP Server.

[3] Section 5 : Replace REMOTE_PEER_FILTER with FILTER option

[4] Section 8 MAP/PEER handling : you may also want to clarify PCP proxy behavior when PCP client uses THIRD_PARTY option.

[5] Section 10.1 Multiple PCP servers : There could be another scenarios that PCP proxy would forward the PCP request to one of the PCP servers depending on the fields set in PCP request (for specific use cases please refer to http://tools.ietf.org/html/draft-rpcw-pcp-pmipv6-serv-discovery-00 , http://tools.ietf.org/html/draft-chen-pcp-mobile-deployment-02#section-8)]

[6] How is it ensured that only the PCP proxy can communicate with the PCP server and not any other PCP client ?
