ddns with noip.com on a 881W

Hi keith

I will use the cisco community to answer your question.  

dynamic dns are now going to charge for the dynamic dns resolution.  So an alternative is to grab one free Dynamic DNS host account at www.noip.com

 

Here is the cli that has to be incorporated into the startup script and then tftp'd to the ISR881W router (reason, cannot paste some of the characters).

 

The debug on my router, as shown below,  indicates that the update may have worked. My free account at noip.com  however does not indicate that a update occured.  This may not be an error.

regards Dave

ip dhcp-client update dns


interface FastEthernet4

 description $WAN$
 ip ddns update hostname myname.no-ip.biz
 ip ddns update no-ip

 ip address dhcp
 ip nat outside
 ip virtual-reassembly in
 duplex auto
 speed auto
end

Then I shut down the wan interface  and did a no shut on the wan interface .  DDNS updated so the debug and interaction with noip.com showed.
