    abstract =  {IPsec offers much promise as a secure remote access mechanism. However, there are a number of differing remote access scenarios, each having some shared and some unique requirements. A thorough understanding of these requirements is necessary in order to effectively evaluate the suitability of a specific set of mechanisms for any particular remote access scenario. This document enumerates the requirements for a number of common remote access scenarios. This memo provides information for the Internet community.},
