Hi David,
thanks for the answer.
See my comments inline...

My router has a built-in support for dynamic DNS service TZO. But it is not
a free service. I will not use this service often, so I don't want to spend
25 bucks on it. Actually, I don't want to use any of these services. I just
want to sent a e-mail to my mailbox, each time I dial in.

That sounds interesting! If I were able to modify my login page of my
router's web interface, I could place the current ip address on this page.
This is brilliant. But I don't know how to hack my firmware.Sounds risky
somehow...

I had some problems with firmware, too. This seems to be a big problem of
SMC. The model I have is a SMC 2804 WBR. There was a firmware upgrade in the
beginning of June. I installed it because they promised to support WPA.
Unfortunately, after applying this firmware upgrade WEP did not work any
more. It took two weeks until they released a new firmware fix, although
they were aware of the problem one day after the erroneous firmware was
released. (I called them and they already knew.)
