Help with DDNS on Cisco router

Hi, on my Cisco 837 router I am trying to get DDNS to work, but it seems to want to send dyndns.org my routers internal address and not the outside assigned by the ISP.

I've added:

ip ddns update method MyDDNS

HTTP

add http://myusrname:mypassword@members.dyndns.org/nic/update?system=dyndns@hostname=my.domain.com&myip=<a>

interval maximum 0 0 5 0

interface Ethernet0

description Inside FW$FW_INSIDE$

ip ddns update hostname my.domain.com

ip ddns update MyDDNS host members.dyndns.org

interface Dialer1

description Outside FW$FW_OUTSIDE$

ip ddns update hostname my.domain.com

ip ddns update MyDDNS host members.dyndns.org

I ran "debug ip ddns update" and got this

Nov 15 21:28:47.017: DYNDNSUPD: Adding DNS mapping for my.domain.com <=> 192.168.2.100 server 63.208.196.96

Nov 15 21:28:47.325: DYNDNSUPD: Another update completed (outstanding=0, total=0)

Nov 15 21:28:47.333: HTTPDNSUPD: Clearing all sessi no ip unreachables

I have just tried adding:

ip ddns update hostname my.domain.com

ip ddns update MyDDNS host members.dyndns.org

to one interface at a time but I get the same results.
