Dynamic DNS functionality

Has anybody configured the ASA's with DDNS to no-ip.com or any other DDNS vendor? I'm having a problem with the DDNS commands and there's no configuration guide on Cisco's website. The Command ref is a little lacking too

If anybody has done this, a sample config would be appreciated

Thanks

Just discovered this hack to update no-ip from ASA

auto-update poll-period 30 3 1

auto-update server   https://user:pass@8.23.224.120/nic/update?hostname=ASA00.zapto.org&myip= source outside

auto-update server   https://user:pass@8.23.224.120/nic/update?hostname=ASA01.zapto.org&myip= source outside

auto-update timeout 1

It should be noted that auto

It should be noted that auto-update timeout 1 as you have it configured here can cause issues.  In my deployment, ASA5506 running 9.4.2.11, when configuring a timeout so small I get "Syslog Error 201008: Disallowing New Connections".  In addition, I use the following configuration for NameCheap.com:

auto-update server https://104.219.249.25/update?auto-update poll-period 30 3 1
auto-update server https://104.219.249.25/update?host=_MYASAHOSTNAME_&domain=_MYDOMAIN_&password=LONGANDCOMPLICATED source OUTSIDEINTERFACE no-verification

Re: It should be noted that auto

Also don't try pasting URLs from notepad as you might need to use "CTRL - V" key combo before ASA lets you enter "?"character, otherwise it will just bring up help menu.

Did you actually try this and got it to work on your ASA? What version?

I'm getting a syntax error on the auto-update server command

ERROR: Invalid remote port

sure I did.

Does your update url work when you paste it into you browser?
