RE: Here's a good one

Hi Greg,

Sounds like it. So, you internal users and ISA Server are using the
internal DNS server to resolve names and the external users are using
the ATT DNS server to resolve names. 

So the external user resolves irc.domain.com to 111.111.111.111 and your
internal users resolve it to 10.10.10.1. Right?

Tom,

AT&T handles DNS for my external resources (web,mx,ftp etc..)

I also run a DNS server on my internal network behind my ISA server for
internal resources.

Is this not split DNS?

Anything external to my network is forwarded to AT&T to resolve via the
forward I have set on the internal DNS.
External requests for internal resources are sent to the External
Interface
of the ISA server and sent through the published rule to it's internal
address.

Thanks

Greg

Hi Greg,

You do not want to loop back through the ISA Server. Configure a split
DNS and directly access the IRC box. I did this last week and there's no
reason to twist through the ISA Server to access internal resoruces.

HTH,
Tom

Folks,
I sure could use some help with a little problem of mine which I can't
seem to figure out.

I've installed a new IM server in my internal network. This IM server in
order to work correctly for internal and external, users
must be able to resolve the host name to the same IP.

Let me see if I can explain this....

The server is running on an internal machine (10.0.0.30)

Our internal DNS server points im.nfti.com to 12.32.70.211

Our external DNS will point im.nfti.com to 12.32.70.211


How would I setup my filters to allow internal users to go out and back
in allowing the ports required for the IM connection?

For external users I figure I would just publish the server maybe? would
that be correct?

Thanks for your help!
