Hi.

Ive got a little problem regarding my dns server configuration, hope you
can help me with this one...

Ive set up a dns server for my domain, and everything is (nearly) ok, just
two problems:

First:
When I surf from my local net, I cant contact my website (www.mydomain.com),
the dns server returns a "no record for www.mydomain.com, cant resolv IP...

The problem is that my website is on an external server, not on a local one,
cause I dont want to have a www server on my net, causes a lot of extra
wor.
How do I tell my bind 8 dns server that the address is not on my local net,
but on an external IP? If I use only the dns server of my ISP, everything
works fine...
How do I tell this in named.conf?

Second:
Im using squid as a proxy, on the same machine with dns, but squid doesnt
understand to use my local dns, but goes directly to my ISP:s dns, causing
intranet.mydomain.com not to be visible, if I dont use squid with my
browser, I can se the address intranet.mydomain.com.
Ive heard that I have to modify resolv.conf in some way, now resolv.conf
looks like:
nameserver my own dns ip
nameserver ISP IP
nameserver ISP IP2

Is this correct?
I heard that I would have to put "forward" in front of my ISP:s IP numbers,
or something?

Thanks for any answers!

That won't work as the second and third name server would never ever be
used as long as the first name server entry is responding.

You need to have your own dns server serve both internal and external
names, and the easiest way is to set it up as a normal caching name
server and then add zone files for your internal names and IP numbers.
Just make sure your name server isn't used from the outside by properly
setting up ACL configuration.

Alternatively, use DNS for external names only and /etc/hosts for internal
names.
