Bump!
This is really annoying... I shouldn't have to risk bricking my new router (E2500) during the flash to DD-WRT just to get a free DDNS service working, when so many other routers allow the free options (such as no-ip.com) by default.
Apparently, the Cisco RV110W can utilize no-ip.com, so why not add that functionality to the Exxxx series?
Please, please upgrade the firmware to allow just a single free DDNS option!
