Dynamic DNS on SRX with dyndns.org

Hello All,

Earlier I tried to setup ddns on SRX with noip.com; but it never worked out.

Now I've got a DNS hostname from dyndns.org (dyn.com) and I've configured SRX with the details:

[edit system services dynamic-dns]
shyam@SRX100# show
client abc.homeip.net {
    server dyndns;
    username shyam;
    password "$9$-9VYoDi.TF/24JDHkQz9ApuOR"; ## SECRET-DATA
    interface pp0.0;
}

In a way this works and in a way it doesn't.

After configuring, when I ping abc.homeip.net from the Internet, it works fine and I get replies from my pp0.0 IP address.

But when I try to telnet abc.homeip.net, it doesn't work. When I try to access it over HTTP, it doesn't work.

shyam@SRX100> show system services dynamic-dns client detail

Hostname     : abc.homeip.net
Server       : members.dyndns.org

The last response as seen above says nochg. Am I missing something here?
