Instant messaging and ISA firewall clients

Clients behind an Exchange 2K - ISA server are able to send instant
messages, but cannot receive them from Internet clients.
The internet client gets: "The following message could not be delivered to
all recipients"

I did everything the Q285781 (XCCC: Configuring Exchange 2000 Instant
Messaging Polling and Fixed Ports) says, but it does not give any
recommendations on how to configure the client or server, besides registry
entries. So, I still have the same problem.
Is there any suggestion or any source I can find the explanation.
Thank you
