tunnel-update

[ciscoreg2]

Hi;

I setup ipv6 tunnel (he.net) and try update dynamic ip with below conf

ip ddns update method he-update
 HTTP     
  add https://username:password@ipv4.tunnelbroker.net/nic/update?hostname=hostname
 interval maximum 0 0 1 0
!
interface Dialer0
 ip ddns update he-update

but it doesn't work. every time it will show error message, anyone knows what's wrong?
Oct 7 15:28:34.868: DYNDNSUPD: Can't create FQDN hostname for update - no default domain
Oct 7 15:28:34.868: DYNDNSUPD: Update aborted - no hostname

Hello,

I think you miss the line below (in bold) under your Dialer interface:

interface Dialer0

ip ddns update hostname Router1.dyndns.org
ip ddns update he-update

The hostname is obviously just an example, it needs to match what you have configured as your hostname.

[ciscoreg2]

it works thanks a lot.

But there is another problem

I got the error message, it seems that there is no certificate for tunnelbroker.net. how to got it?

HTTPDNSUPD: Call returned Request Aborted, update of ipv4.tunnelbroker.net <=> xxx.xxx.xxx.xxx failed

Hello,

what are the source and destination IP addresses/interfaces for your tunnel ? Can you post the full configuration of your router ?

[ciscoreg2]

please see my conf

Hello,

I think the problem is that Hurricane Electric doesn't use self signed certificates anymore. You need to replace it with the tunnelbroker CA, which you can find in the link below (scroll down to the Hurricane Electric section):
