-------------------------+--------------------------------------------------
 This is a placeholder/discussion ticket for IPv6 support with torouter.
 IPv6
 support is not a blocker or high priority at this time, and there is some
 concern about trusting "new" IPv6 daemons and code paths (citation
 needed!).

 One way way IPv6 would work is that "downstream" devices connecting to the
 torouter (over the open wifi network or the local ethernet port) would
 auto-configure addresses from a site-local prefix (not globaly routed) and
 the
 torouter (via tsocks) would effectively provide NAT. With this scheme it
 would
 be possible to enable "downstream" IPv6 connectivity without proper
 "upstream"
 support (or vica versa).

 "Upstream" IPv6 would require at least:

 - tor network and daemon support ([wiki:org/roadmaps/Tor/IPv6 roadmap])
 - ntp client support
 - automatic SLAAC/DHCPv6 configuration

 Presumably SLAAC would use a randomized address (not based on the ethernet
 MAC
 address). Bootstrap upstream DNS could go straight to global DNS servers
 known
 to return both AAAA records and reply to requests over IPv6.

 "Downstream" IPv6 would require at least:

 - a (hardened?) radvd
 - IPv6 configuration and support of the onboard recursive DNS servers
 (ttdnsd, unbound, dnsmasq)
 - support in tsocks
 - appropriate firewall rules
 - extension of the web interface to display and configure IPv6 options

 In either case, kernel and iptable support would need to be enabled and
 the web
 interface extended to display and configure IPv6 options.
