ShareTechnote 2015-10-13 · 13 = Communication Administratively Prohibited - generated if a router cannot forward a packet due to administrative filtering . This is the code value for an administrative denial, which indicates that a router is filtering a port and is not permitting traffic to pass. The packet is typically seen when traffic is refused to pass through a RFC 6145 - IP/ICMP Translation Algorithm 2020-4-19 · RFC 6145 IPv4/IPv6 Translation April 2011 1.Introduction and Motivation This document is a product of the 2008-2010 effort to define a replacement for NAT-PT [] (which was changed to Historic status when [] was published in 2007).It is directly derived from Erik Nordmark's "Stateless IP/ICMP Translation Algorithm (SIIT)" [], which provides stateless translation between IPv4 [] and IPv6 [], and [Router Products] Error message IP address unreachable in
