QuoteDo I have to turn off ipv4 on the Mac if I'm using ipv6?
QuoteHow does "Protocol 41" fit into the picture. Do I need to do anything to my Cisco 871 to support Protocol 41? To OS X?
QuoteDoes the CISCO have to be enabled with "ipv6 uniast-routing" for OS X "Automatically" to work?
QuoteDO I add a DNS entry for ipv6?
Quote from: broquea on December 08, 2009, 01:11:00 PM/48 and /64 do not mean how many IPs per block, they are block sizes, with a single /64 having 18 quintillion IPv6 addresses, and a /48 has 65536 /64 subnet allocations.you'll want ipv6 unicast-routing enabled.I think if you simply put like 2001:470:8:444::1/64 on your LAN facing interface on the cisco, that it will automatically start to use RA to get your LAN machines configured. I believe you have to explicitly set "ipv6 nd suppress-ra" or similar on that LAN facing interface to not use RA.
Quote from: jimb on December 08, 2009, 03:13:29 PMLOL. So on a Cisco, you have to explicitely tell it to route ipv6 (even though it's a router), but explicitly tell it NOT to do router advertisements on an IPv6 configured interface for it not to do it? Please tell me it wont do RA unless you enable routing at least? (haven't done much IPv6 on Ciscos, obviously) :P

I use MSDNS and I need to manually insert the IP addresses into my DNS server (both v4 and v6)For external lookups, you can just give OSx the address of your local dns server (v4 or v6) or use DNS from HE (in that case, yes, use both addresses)

I put 2001:470:20::2 into the OS X DNS list for the MacBook and with ipv4 and ipv6 enabled on OS X, a browser request to http://ipv6.he.net/ goes over port 80 instead of the tunnel...I turn ipv4 off and it seems OS X ipv6 "automatic" doesn't find the router. I did add "ipv6 unicast-routing" to the Cisco 871.I'm still confused about the configuration settings. Can someone maybe try to explain (without too many acronyms) what is going on here? When OS X is in IPv6 "automatic" mode how does the client get an ipv6 IP address? Is the IP traffic sent as lower level packets to the router which sends the traffic down the tunnel and the IP address of the router is used? So is the OS X client and the router both using IP address "2001:470:7:444::2" in my configuration?In the tunnelbroker.net suggested configuration for CISCO routers in the suggested IOS commands. Why isn't the command "ipv6 unicast-routing" included as part of the suggested configuration for ipv6 listed here:configure terminalinterface Tunnel0 description Hurricane Electric IPv6 Tunnel Broker no ip address ipv6 enable ipv6 address 2001:470:7:444::2/64 tunnel source 188.8.131.52 tunnel destination 184.108.40.206 tunnel mode ipv6ipipv6 route ::/0 Tunnel0endwrite"
