NAT/Firewall function, and misc updates to CWMP ALG requirements.
v3 - 10/1/2012 -- Added CWMP redirect interworking, clarified TLS requirements, clarified how ALG
related to TR69 architecture and leveraged a subset of Gateway mechanisms.
v4 -10/8/2012 -- Generalized CWMPALG object as HTTPALG to cover HHPT and CWMP
v5 - 10/15/12 -- Made the Data NAT/Firewall, CWMP ALG, and HTTP ALG functions optional to

NAT/Firewall.
v6 - 10/22/2012 -- Updated informative text to describe Twice-NAT.
v7 - 10/29/2012 -- Updated data model to reflect herarchy of Provisioning Gateway types.

NOTE TO AUTHORS - INSTRUCTIONS FOR COMPLETING PROPOSED CHANGES IN THE SECTIONS BELOW:
For ease in reviewing and editing, please use the following formatting on changes. For modified and/or deleted text in the “original

AND PARAGRAPH THAT EACH CHANGE AFFECTS. Detailed instructions to the document editor are always welcome.
DETAILED PROBLEM DESCRIPTION
This EC adds Provisioning Gateway functionality to the ESG. This new functionality will enable the Service
Provider to configure the ESG so that it can act as a Gateway device for provisioning traffic exchanged between the
Service Provider and Enterprise networks to provision hosted IP-Centrex SIP endpoints located in the enterprise
network.
Without this function, the provisioning traffic for enterprise SIP endpoints must traverse the Enterprise-owned and
operated NAT/Firewall, where it may be blocked by Firewal rules configured by the enterprise.
PROPOSED SPECIFICATION CHANGES (Please include section number, title, and paragraph)
Please note Engineering Changes may only address one technical issue in one specification, although it may require changes to
multiple sections in the specification. Please itemize each change as follows. If you have multiple changes and some are
technical and some are editorial (but all address the same issue), please indicate which is which in addition to selecting “both”
under the type of change above. Note: Technical changes may require a vendor to change the design of the product. Editorial
changes are points of clarification or clean-up but would not generally require a change to the product.
