Hi Ron,

Attached is the XLS spreadsheet that, according to Cisco Feature Navigator at http://cisco.com/go/fn , lists all IOSes for 2621XM that support DDNS.

The guide to configuring dynamic DNS on IOS can be found here:

http://www.cisco.com/en/US/docs/ios/12_3/12_3y/12_3ya8/gt_ddns.html

Of course please feel welcome to ask further!

Best regards,

Peter

Hi Sir Peter,

Thanks for the information. Do you know why on the Cisco IOS download page show only IOS up to 12.3 & no 12.4?

I will try this & feedback you. Thanks again.

Actually it shows 12.4 for the 2621XM.

However whatever it shows, in practice images for these old routers cannot be downloaded from cisco, because the are EoS already, and no new support contract can be purchased.
