In my case the DNS entries are dynamically recd from the ISP and are available
in /var/run/ppp/resolv.conf.
But how will the desktops get this entry. I have the problem on the desktop
side....
I am sure of one thing, the DNS Server IP on the desktop has to be the one of
my Proxy Server.
So the next question is, which / how to run a small DNS server / DNS proxy
Server, which will fwd all DNS request recd from desktops to the ISP's DNS
server, and feed the reply back to the desktops....
Thx.
