Problem with internal DNS - dyndns

[chethanzmail]

I am having trouble with resolving myaddress.dyndns.org name when I am in my internal network. This is how my setup looks like currently:

- Gateway server running debian lenny
-- Runs ddclient to update IP address
-- Has a webpage that is on the dmz with the same name https : // myaddress.dyndns.org which is accessible externally (from outside our network), but not internally
What is amusing is that the setup worked fine until recently, but all of a sudden it stopped resolving myname.dyndns.org when trying to access it internally.

Could somebody provide some direction please?

Thanks!

Can you resolve anything internally?
Have you check dyndns to ensure your records are still being hosted?
Can you post the output of 'dig myaddress.dyndns.org'?

Thanks for your reply. I was able to resolve this. I had a dynamic IP from my ISP and this was hardwired in my firewall (and obviously not setup to be updated by the ddclient). I updated this manually and everything works as before. Will script this up to ensure I don't have to do this manually all the time.

Thanks!
