Make sure to right click on the icon for the app and save the ICA file.
Edit it in notepad and see what IP address you are getting there. Verify
it is the one you can telnet to from the internet.

Ron,

Thanks for the reply it was incredibly helpful and I think I'm almost
there with this setup.

Now everything is setup I can telnet into the metaframe server from the
internet on ports 1494 & 8081 (our XML port).

The web pages enumerate the application list and generate the webpages.

However, when I try to run one of the apps. I get "The citrix metaframe
server you have selected is not accepting connections".

Both the server is active and listening and logons are enabled.

Can anyone tell me where the problem could lie?

Any input appreciated

Stu Pittwood

Comments in line:
In a back-to-back DMZ where both firewalls are performing NAT what
should the alternate address on the metaframe farm be? the address the
address on the internal firewall or the address on the external
firewall?
=3D3D3D20
Depends: If the servers are behind the second firewall and the first
(outside) nats to an address that the second (inside) then NATs again
and the clients are connecting via this NAT string and not via the CSG
then the OUTSIDE address of the NAT on the outside firewall is the
altaddr. This is the address that the client (over the internet) will
route to.

If they are using the CSG then some NAT and altaddr may still be
required or you may have to play with XML DNS name resolution


Also, in the Nfuse.conf file what should the serve be specified as?
Again the address on the internal firewall or the external firewall?

HUH?  If the NFUse servers are between the firewalls then use the
address that the Web server can use to reach the MF boxes. I assume the
address on the second (internal)firewall.
=3D3D3D20

Final question, is it possible for two nfuse sites to be run on one web
server looking at different addresses for the metaframe server?
Not with NFuse 1.7-1.8/2.0

Get an older copy of 1.61 with Columbia and you can copy that directory
to anywhere you want and run duplicate sites.
