Hi,
I've updated my "IPv6 Firewalling Considerations" draft, and it will be
available in the repositories before the meeting. In the mean time, it
can be found at:
http://www.netcore.fi/pekkas/ietf/draft-savola-v6ops-firewalling-01.txt
As a sugar on top to encourage you folks to read it, I've added (in an
appendix) an IPv6-specific DoS reflection attack (with amplification)
involving multicast. I hope that's enough to make folks read & comment
;-)
Abstract:
There are quite a few potential problems regarding firewalling or
packet filtering in IPv6 environment. These include slight ambiguity
in the IPv6 specification, problems parsing packets beyond unknown
Extension Headers and Destination Options, and introduction of end-
to-end encrypted traffic and peer-to-peer applications. There may
also be need to extend packet matching to include some Extension
Header or Destination Option fields. This draft discusses these
issues to raise awareness and proposes some tentative solutions or
workarounds.
