This is a request to: * Support IPv6 packet reassembly with the "reass" command in ipfw. * Update the documentation and/or ignore the ip6 reass command (to avoid someone bricking a device) in the mean time Notes: I presume this is the same problem as reported earlier by someone else on the freebsd-ipfw list: http://lists.freebsd.org/pipermail/freebsd-ipfw/2011-October/004918.html The bug report/feature request is meant to keep track of that issue. >How-To-Repeat: Steps to reproduce: 1. Add the following rules to ipfw: # sysctl net.inet.ip.fw.one_pass=0 # ipfw add 100 reass ipv6 from any to any in 2. Try to connect to the device (with any means, e.g. ssh over either IPv4 or IPv6) Expected result: I expect the device to be reachable Actual result: I bricked my device >Fix: >Release-Note: >Audit-Trail: >Unformatted:
