We have a similar setup and had a few similar issues. What ports did you
open up and to what boxes? Do you have the only Zone DC's enumerate program
neighbourhood checked on the Farm properties on the Zones tab ?

Subject: [THIN] Clients behind firewalls
Hi there,
Environment: MF XP1.0 on Windows 2000
We have a couple of users who connect from a 3rd party site. Between this
site and the server farm, firewalls have been put in place and rules have
been created to allow the Citrix traffic. Our farm consists of 20 servers.
These clients should only connect to 6 of the servers (2 are dedicated data
collectors and 4 are actual load balanced application servers), therefore
firewall is open only to these 4 boxes.
When the users connect via the Program Neighbourhood, they get the error
message "Cannot connect to the Citrix MetaFrame server. There is no route to
the specified subnet address".
The issue is not critical as refreshing 3 times usually clears the issue
however it is annoying. I received some network trace logs which clearly
show that the clients try to connect to servers where they should not.
I assume a quick workaround would be to add all the servers in the firewall
rules, but I would rather know what is really going on.
Has anyone a clear view on this?
Thanks!
