[Elecraft] Remoting the K2

[Brett Howard]

The only problem is that the location with the dynamic IP is the station in
which he's connecting from.  And if he was to lock down the connection at
the firewall to an IP he'd have to change that whenever he got a new dynamic
address.  

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.

73,
