Thank You,

(I should have said I wanted to change my shell domain name, sorry.)

I CHANGED THIS FILE:

 /etc/dhclient-eth0.conf

I ADDED:

supersede domain-name localhost.localdomain; (no quotes)

man dhcp-options says:

The  domain-name  data  type  specifies  a  domain name, which must not be
      enclosed in double quotes.   This data type is not used for any  exist-
      ing DHCP options.   The domain name is stored just as if it were a text
      option.

Do I really need a Nat router?
