[lycbe31@hotmail.com]

hi guys,

i am fresh in Cisco devices. i got a ASA5506X and want update my domain to NameCheap. 

i followed https://www.namecheap.com/support/knowledgebase/article.aspx/29/11/how-do-i-use-a-browser-to-dynamically-update-the-hosts-ip

and successfully build a URL for updating, i also test it on browser, it did works.

however, i copy this URL to configuration->DNS->dynamic DNS->dynamic DNS interface:hostname(with a method which update each 30seconds)

it still not work at all

outside port:

interface GigabitEthernet1/1
    nameif outside
    security-level 0
    ddns update hostname dynamicdns.park-your-domain.com/update?host=myhost&domain=domainname&password=xxxxxxxxxxxxxxxxxxx
    ddns update vpn.mindhole.online
    dhcp client update dns server both
    pppoe client vpdn group asa5506
    ip address pppoe 
!

ddns update method mymethod
    ddns both
    interval maximum 0 0 0 30
!

it also have a 'dns domain-lookup outside'

could anyone help my about this?

thanks

hi guys,

i solved this problem:

thanks:

https://community.cisco.com/t5/firewalls/dynamic-dns-functionality/td-p/816451

and 

https://community.cisco.com/t5/routing/ddns-issue-ddns-not-updating/td-p/2886521

there are little changes:

auto-update poll-period 30 3 1
auto-update server https://dynamicdns.park-your-domain.com/update?auto-update verify-certificate
auto-update server https://dynamicdns.park-your-domain.com/update?host=[host]&domain=[domain]&password=d[password] no-verification

it will auto change dynamicdns.park-your-domain.com to ip

and it works in ASA9.8(1)
