[Config] DynDNS Update interval question
I am trying to install DynDNS in a Cisco router. The config of the router is fine and the system is up and running.
I would like to make sure that my DynDNS config is fine as I've never dealt with it before and additionally I would like to know what the update interval should be...?
This is the DynDNS config currently:
ip ddns update method <name>
interval maximum 28 0 0 0
interval minimum 0 12 0 0
Additionally is the DDNS string correct too??
I have seen this system update previously while running:
and all ACLs etc... have been set to 'allow' the service.
Can anybody assist me or suggest anything to be able to be sure that the system is working properly?
I did run
debug ddns ....
and monitored the output of the console on the vty session I was running however, I did not see any output?
help at all?

According to your syntax I tried:
ip domain name <hostname>
ip ddns update method <ddns_name>
interval maximum 0 0 2 0
interval minimum 0 0 2 0
With the Dialer interface being provisioned as such:
ip ddns update hostname <hostname>
ip ddns update <ddns_name>
ip address negotiated
ip access-group 102 in
ip inspect INBOUND in
ip inspect OUTBOUND out
ip nat outside
dialer pool 1
ppp authentication chap callin
ppp chap hostname <chap_hostname>
ppp chap password 7 <scrt_passwd>
ppp pap sent-username <pap_uname> password 7 <pap_passwd>
ppp ipcp dns request
ppp ipcp wins request
crypto map mymap
debug ip ddns update
does not yield anything with only 2 minute intervals.....
I **will** specify 28 days later after I start seeing something in the debug console....
Am monitoring by:
lin vty 0 4
Something is off definitely!
I had similar issues like this a while back when getting my HE dns and ipv6 updater working...
The trick seems to be to either shut/no shut the interface that the dyndns is running on. This will obviously cause you to lose internet access.
in your case...
clear int dialer 1
Try that and let me know how it goes.
