IP address of Dlink router

I want to run a Linux box behind a Dlink DI-624 router. I want to allow
ssh into the Linux box and I can see how to configure the router to
forward ssh to the PC. But if the router gets an IP address dynamically,
how can this address be discovered by the PC? (If the PC has the
address, it can use dyndns to make it known to ssh clients.)

Maybe not very "advanced" , but extremely practical : www.myip.com
(I use wget and grep to grasp it)

And by the way , DLInk routers do often have an interface to dyndns
(dynamic ip) to update directly. So maybe you even don't have to care at
all.

I hacked the firmware of my DI-704 to show its WAN IP on its login page,
so I could monitor it with a Perl LWP deamon script without having to log
into its compilcated mixture of frames/javascript. But I was careful to
replace text in its html login page with exact same number of variable
charcters, so I would not displace its binary code (no change in file
size).

Dynamic DNS services should have an update client that can run as a daemon
behind a router and tickle them at regular intervals to grab your
connecting public IP. I know that no-ip.com does. Although, I currently
use Linux for pppoe/firewall/masq, so I run it once from /etc/ppp/ip-up
which automatically runs whenever getting new ppp IP.

I also heard of one (dyndns.org?) that will stop doing DNS for you if you
update them too often when your IP has not changed.
