Dynamic DNS functionality

ciscors — Mon, 11 Mar 2019 10:38:06 GMT

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

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

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

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.
