6in4 with dd-wrt
« on: August 29, 2011, 08:45:28 PM »

i'm using the script found on this page.

http://www.dd-wrt.com/wiki/index.php/IPv6_setup_Hurricane_Electric_Tunnel_Broker

my problem is that i can't seem to get the settings correct. these are mine currently.

#basic connection settings
SERVER_IPV4_ADDR="72.52.104.74"
CLIENT_IPV6_ADDR="2001:470:1f04:1ef4::1337"
ROUTED_64_ADDR="2001:470:1f05:1ef3::0"

i think my problem is with the last one. since the example syntax on the bottom shows an actual ipv6 address instead of an ipv6 prefix, i'm confused as to what it should be.

edit: ok figured it out. i deleted the 0 and added /64 at the end. it was the prefix after all. however i still have issues as the tunnel does not appear to work. doing "ip -6 route show" yields this result.

Code: [Select]

i believe there is supposed to be one more entry beginning with 2001 that's missing.

Ok I highly doubt this is the client ipv6 address on your tunnel

CLIENT_IPV6_ADDR="2001:470:1f04:1ef4::1337"

Every tunnel I have ever seen ends with 2 for the client endpoint

Agreed with John.

Furthermore

CLIENT_IPV6_ADDR="2001:470:1f04:1ef4::1337"
ROUTED_64_ADDR="2001:470:1f05:1ef3::0"

The networks only differ on the third group and the two you've listed differ on both the third and fourth.

i added /64 to the client ipv6 addr and it started working...

as for 1337 at the end, i remember i could change it to that and still have it work when i set the tunnel up directly on my windows 7 machine. since it's a /64 i should be able to change the last 4 fields.
