ASUS router configuration

jlightfoot · April 29, 2014, 11:41:15 AM

I'm trying to move my HE tunnel to my ASUS RT-AC66U but it isn't working. I followed the directions on this post (https://forums.he.net/index.php?topic=2680.0) but am unsuccessful and would like to check my settings. In particular, I want to make sure that the prefixes are right and the LAN ipv6 address seems funny to me.

Asus setting Tunnelbroker details Comment
Connection type "Tunnel 6in4"
Server IPv4 209.51.161.14 My tunnelbroker endpoint
Client IPv6 Address 2001:470:1f06:112e::2 From my tunnel configuration
IPv6 Prefix Length "64"
Tunnel MTU "0"
Tunnel TTL "255"
LAN IPv6 Prefix 2001:470:1f06:112e
LAN Prefix Length "64"
LAN IPv6 Address ::5847:b97f:f00:0:0:1 This seems wrong to me, but I don't have the ability to change it.
IPv6 DNS Server 1 2620:0:ccc::2
Enable RA Enabled

Any help would be appreciated. Thanks.

Your ipv6 lan prefix is incorrect...it should not be the same as your tunnel prefix

Thanks, how do I determine what it should be?

cholzhauer · April 29, 2014, 12:38:38 PM

Under your tunnel details page there should be a listing of LAN IPv6 range and Tunnel IPv6 range...same place you request a /48

Here's what the HE tunnel configuration page shows:

IPv6 Tunnel Endpoints:
Server IPv4 Address:209.51.161.14
Server IPv6 Address:2001:470:1f06:112e::1/64
Client IPv4 Address:x.x.x.x
Client IPv6 Address:2001:470:1f06:112e::2/64

Routed IPv6 Prefixes:
Routed /64:2001:470:1f07:112e::/64
Routed /48:Assign /48

I don't see two separate prefixes, everything looks the same.

QuoteServer IPv6 Address:2001:470:1f06:112e::1/64

QuoteRouted /64:2001:470:1f07:112e::/64

Even the 1f07 chunk of the prefix is BOLDED for people in the broker interface.

Thanks, tried fixing the prefix but haven't made any progress. I don't seem to be getting an ipv6 address from the RA.

Ifconfig on my router shows:

v6in4 Link encap:IPv6-in-IPv4

Actually, I've made progress. When I do a traceroute to ipv6.google.com from the router I get a valid response over ipv6:

# traceroute ipv6.google.com

But I can only do that from my router, not from a client on my network. Now it seems like the RA function isn't giving my clients an ipv6 address.

Still stuck.

I've found that if I switch the connection type to 6rd, my clients get a global ipv6 address, but I can't get to the Internet via ipv6. The other thing I think is strange is that my ipconfig shows DHCPv6 information, I'm not sure where that came from.

Finally got it.

I used 6in4. My problem was that the LAN ipv6 prefix needed to end in :: . Now the LAN ipv6 address is right and all is working. Thanks for the help.
