I have had my IPv6 tunnel working on my single Windows workstation for the last few years, but now have the itch to provide the rest of my network with IPv6 routed through this Windows (8.1 now) machine. I found an older article on here on how to enable routing to the rest of the LAN using netsh commands, but which IPv6 addresses to use were not clear, and I don't want to break my system just guessing. Here is how I am currently configured (from my notes):
To enable IPv6 on Win7/Win8 for Garrick's Hurricane Electric IP range
(assuming 192.168.242.233 is being NATted through ASA and protocol 41 is being passed through)
netsh interface teredo set state disabled
netsh interface ipv6 add v6v4tunnel IP6Tunnel 192.168.242.233 216.218.226.238
netsh interface ipv6 add address IP6Tunnel 2001:470:a:64::2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:a:64::1
That gets me IPv6 connectivity on my box (through an ASA5505 configured to pass protocol 41 through and static NAT configured). Here is my configuration as provided by HE:
IPv6 Tunnel Endpoints
Server IPv4 Address:216.218.226.238
Server IPv6 Address:2001:470:a:64::1/64
Client IPv4 Address:50.197.86.211
Client IPv6 Address:2001:470:a:64::2/64
Routed IPv6 Prefixes
Routed /64:2001:470:b:64::/64
Routed /48:2001:470:e8f9::/48
The /48 is new today, didn't know if I needed to use that for the internal network or if I would just hand out IPs from the /64 (not like there isn't enough). From the
prior post in this forum, I think I have to do something like this (Ethernet 4 is the virtual interface on my system that Hyper-V set up, with all of my existing IPv4 config on it already):
netsh int ipv6 set interface IP6Tunnel forwarding=enabled
netsh int ipv6 set interface "Ethernet 4" forwarding=enabled advertise=enabled
netsh int ipv6 add address "Ethernet 4" 2001:470:e8f9::1
netsh int ipv6 set route 2001:470:e8f9::/48 "Ethernet 4" publish=yes
netsh int ipv6 set route ::/0 IP6Tunnel 2001:470:e8f9::1 publish=yes
My only worry is that it looks like I would end up having two different default routes set up, and two different IPv6 addresses on my machine. Can someone sanity-check me and correct where necessary? Thanks muchly!
