16  General IPv6 Topics / IPv6 on Linux & BSD & Mac / Re: CentOS routing help on: December 21, 2010, 11:00:28 am
   Routed /64:    2001:470:1d:417::/64

so I made some changes to the script

modprobe ipv6
ip tunnel add he-ipv6 mode sit remote 216.66.38.58 local 75.152.109.214 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:1d:417::2/64  dev he-ipv6
ip route add ::/0 dev he-ipv6
ip addr add 2001:470:b115::1:1/64 dev eth0
ip addr add 2001:470:b115::2:1/64 dev eth1
ip -f inet6 addr
sysctl -w net.ipv6.conf.all.forwarding=1

I think this right?
so on the host machine I would use say 2001:470:b115::3:1/64 dev eth0 ? and what about the next machine on the LAN i could use 2001:470:b115::3:2/64 ?

but eth1 and LAN machine are connected via a swith so they should be on the same network 2001:470:b115::2:2/64 ?

I am going to restart the router with the canges and see if anything works.

also how do i make the default route: 2001:db8:1:1::1  For eth0 on my tunnel machine?

Routed /48:    2001:470:b115::/48

the 2001:470:b115:: is my routable address space so using    2001:470:b115::X should be alright?

I am going to make the change noted above and let you know.

Good day, I have set obtained a /48 and succseffly set up the tunnel, my router can ping6 ipv6.google.com and I get a responce, I can also visit it on my browser. however my other host on my lan can ping only the directly connected interface and nothing else. Any help would be aprechiated. Below is the router set up
