D-Link and Cisco support IPv6. The D-Link-supported routers (a firmware update may be needed) are: DI-784 abg, DI-524 bg, DI-624 bg, WBR-1310 g, WBR-2310 g rangebooster, DIR-615 n. See p. 16 of Ref: http://www.ipv6.org.tw/summit2008/doc/1-4-4.pdf
On p. 15, they say: "Not only [does D-Link] meet IPv6 Ready logo requirements, but also upper layer IPv6 connection mechanisms: Static IP, DHCPv6 (Stateful), DHCPv6 (Stateless), PPPoE, IPv6/IPv4 Tunneling, 6to4 Tunneling, Autoconfiguration, Link-Local connection."
Personally, I use a free IPv6 tunnel service from http://www.tunnelbroker.net/ provided by Hurricane Electric.
I don't use Cisco at home, but IPv6 information is at http://www.cisco.com/ipv6/
Firefox 1.5.0.9 and 2.0.0.1 (and Thunderbird 1.5.0.9) have been released. All include security fixes. But why are Firefox 1.5.0.8 users being offered 1.5.0.9?
With your bare hands?!?
