adding a host/principal behind a firewall

[Steve Blackwell]

Hello,

I'm a newbie at Kerberos but I have set up my computers at work to use it. 
So far, so good.

Now I want to add my home computer to the realm. My home computer is 
behind a firewall so it has an IP address of 192.168.1.x and a hostname of 
localhost at localdomain. The IP address of the firewall is set by my ISP 
using DHCP.

Is it possible to add this computer to my realm and if so what name do I 
use?

Thanks,
Steve.
