I've just been through some of this with a lot of help with articles on the
web site. I'll try to summise some of what I learned.
If you also want TS on the ISA you have to change its port such that web
publishing can listen on the standard port of 3389 and pass it on to another
server. Note that if you're changing the port remotely make sure you add
packet filters for the new port or you'll end up stranded and unable to
connect...!
You can then publish your terminal server but as you say, one IP address is
needed per terminal server as publishing can onlu listen on one port per IP
address.
I suspect the best way to manage multiple server will be to login to one and
then TS from there to the others once you are "inside".
Chris.

Is this saying that every TS server has to have a public name and IP
address? It would seem like this could be a real problem if you had a lot
of machines that you wanted to be able to manage via the web through TS.
It appears to me that a TS publishing rule simply maps an external IP
address on the ISA machine to an internal IP address. So would you need a
separate publishing rule for each TS server?
Thanks.

The external client has to be able to resolve whatever name you enter in the
"server" field to an ISA external IP so that it can be routed to the proper
TS server behind it.
You also have to have a TS publishing rule to the server you're trying to
connect to.

I have Terminal Server set up on two of our servers. From inside the
firewall everything works fine. Both the Windows and web clients can access
both machines. The Windows client also works fine over the VPN. However,
if I try to log on from outside the firewall with the web client the server
cannot be found. The actual error message is "Error connecting to terminal
server: ungerras". (ungerras is an internal name, not published on the
web.) However, if I leave the server name blank when logging on, it
actually connects to ungerras. It indicates that it is logged onto
<file://www.mydomain.com> www.mydomain.com (where "mydomain" is out
published web site), but it is actually connecting to ungerras (on a
different machine). However, there doesn't seem to be any way to connect to
the other server (which is actually running on the IIS machine that we are
connecting through).
I'm curious about what is going on here, and it's clear that I don't
understand how the server name is being resolved. Any help would be
appreciated.
(I believe that we are set up following the instructions on the
isaserver.org web site.)
