Some folks use multi-homed servers, forbidding everything but TCP 1494, and UDP 1604 on that interface.

IANA also lists 2512, 2513, and 2598 (TCP/UDP) as belonging to Citrix, but so far as I know, these are not necessary for remote clients.

Anybody hear anything about ICA itself being dangerous? (Other than the fact that it gives folks a username/PW login box, nauseating, but heck, allowing anybody to login remotely is nauseating.)

I hope you start to have fun, Ken! ;-)

Has anyone actually managed to make a Citrix Metaframe server - published
application actually work through a firewall? If so, would you mind sharing
a few of details?

We have been able to get access to the Metaframe server directly, but are
having one hell of a time trying to get access to the published app.

Alternatively, if anyone has any _good_ sources of info regarding the use of
the UDP/1604 traffic by the ICA clients and/or servers, in conjunction with
the master browser server, and/or "alternate address" configuration, that
would be very much appreciated.

Just not having any fun on this project...
