newbie: transfering DNS-Server adresses from router to clients

How can I transfer the DNS-Server adresses that my DSL-router gets
from my provider to my Win- and Linux-Clients automatically?
(2 to 5 PC's, dial-on-demand, DSL or ISDN, router will never
become DHCP-server)

Thats what I do so far: I look at /etc/resolve.conf of my router
and put the server adresses into the resolve.conf of the linux
clients and somewhere into the config of Win-Clients. I works
as long as the provider changes the adresses of the DNS-servers.
When the DNS-server adresses are changed I changes the
DNS-Server adresses in every client manually. I serve networks
with 2 to 5 PC`s only, its not much work. But I want to
implement a solution that does this automatically.

I've heard of DHCP that delivers the somewhat DNS-servers automatically.
But the internet router is not the master PC with somewhat DHCP-server.
Does that DNS stuff work with DHCP when the dial-on-demand router
gets the DNS-adresses dynamically somewhen?

I've heard of DNS-server that could be installed on the router.
(my router is a fli4l floppy router and DNS-server may be installed)

thx

Some routers do DNS forwarding or caching automatically if you point to
their IP. Otherwise, you could always run your own caching nameserver on
a Linux box. I installed bind9 because my adsl ISP's DNS was sluggish
when I first got it, and added forward and reverse zones for my LAN (so I
do not have to mess with /etc/hosts except for a machine's own name).

And why not run a DNS cache serveur on your router ?

Like this, you point your client DNS on your router, and you have nothing
to change when your ISP DNS change.

No problem with a DNS cache server on your router. You can set this
address in your DHCP serveur as the primary DNS server. And so you even
don't need to set your client manualy.

Yes there is already a DNS server on fli4l :

Set the DNS in your Windows and Linux station to your router ip address.
