Fritz Box 5140
« on: January 21, 2013, 02:53:19 AM »

ok the fritz box 5140 doesn't support ipv6 out of the box (pun intended)
so I compiled a freetz image with a modified kernel
added the ipv6 module. set it to load on boot
set the box to add the interface and tunnel
also added dnsmasq (might replace it with radvd, at least radvd gave my local pc an ipv6 address)
the dnsmasq problem is secondary

the primary problem is dropped packets.

the fb 5140 has 1 dsl plug and 4 lan plugs
the connection to the internet is done over the dsl interface and the local PCs are connected to the LAN ports.
my isp is 1&1 Germany.

/tmp/flash/mod/rc.custom
Code: [Select]
modprobe ipv6
ip tunnel add he-ipv6 mode sit remote 216.66.80.30 local 192.168.178.1 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:1f0a:c53::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6

this is all done on the box

do I need to create a bridge or what would I have to do to get it to work?
