DDNS

[burtsbees]

Has anyone successfully configured dynamic dns in a Cisco router (with dyndns.org), and if so, could you please provide a sample config? Mine does not seem to work.
Also, if it cannot work, could I just point the dns server the router uses to a Windows 2003 Server, and maybe use some dynamic dns program pointing to dyndns.org on the server? Thanks.

I managed to get it to work with dyndns.org, however I think they have some policy whereby they only accept updates at certain intervals?

ip ddns update method test
 HTTP
  add [URL unfurl="true"]http://username:password@members.dyndns.org/nic/update?system=[/URL]
dyndns&hostname=hostname.homedns.org&myip=<a>
 interval maximum 28 0 0 0
 interval minimum 1 0 0 0
!
interface Dialer1
 ip ddns update test

It does work but it gets out of sync easily when you renegotiate the IP address.

Details on CCO here about to configure it:

Note how you get it to recognise a '?' without it trying to help you.........

I tried to put ip ddns update xxx on int di0 (my outgoing interface), but it came back with "%DYNUPD: warning: method test is not configured"...

Also, did you configure "ip ddns update hostname xxx.dyndns.org" on the interface?

I know this is the router forum but do any of you know how or if you can do this with a PIX501?

 

[burtsbees]

Try using SDM---if you can, the option will be available.

No, a pix 501 doesn't support dynamic dns.

On a side note, with a pix running 6.x code and less its called a PDM not an SDM.

Ah...thanks. Duly noted. Si puo' anche notare que.

ya the ? is a good trick.. i was stuck looking for that one a few months ago.

Note Before entering the question mark (?) character, press the control (Ctrl) key and the v key together on your keyboard. This will allow you to enter the ? without the software interpreting the ? as a help query.
