A router with DDNS support can do this automatically. Plus, the firewall
is only open to a piece of hardware that converts serial port data into
TCP port data... not to a PC. Nobody is going to hack into a black box
with dedicated firmware when there are millions of Windows machines out
there to hack into. There is very little risk in that, unless I'm
missing something (not unheard of, BTW ;-)

It's a bad idea to tie a secure connection to a resolveable name. Those are
much easier to spoof than an IP. But I guess its at least still better than
leaving it wide open. Although I don't think most firewalls will allow you
to put in a resolveable address. That would mean it would have to
technically re-resolve it whenever each packet came in. Or after each DNS
cache flush.

Hi Stephen. Check out DynDNS. They provide a free service that
correlates an alphanumeric IP alias address with your currently assigned
numeric IP address. A utility on your PC provides your address to their
server. The service is called DDNS. Some routers have this built in.
Instead of an address like nnn.nnn.nnn.nnn, the address of your PC
becomes something like g4dsp.homeip.net. The server finds you based on
its knowledge of your actual address. I believe this is discussed in one
of the sections of my website (www.telepostinc.com) under the heading
Remote Base Station Related Stuff...
I posted an email about this to the list in response to your earlier
inquiry, but I forgot to change the Subject (it was posted from a digest
entry), so you may have missed it. There is lots of interesting info
about the remote control system I use there.

Thanks to all with their help and advice which I must now mull over. One
thing that has (rather late in the day) occurred to me is that I do not
have
a static IP address from my ISP. So I could, presumably, look up the
address given and use that, accepting that I shall have to change the
settings every time I reboot the router which is very rarely.
