Passthru and cluster

Is this supposed to work?

I have 4 Passthru server. Their Passthru configuration are the same.

Let say their Names are:

Passthru1

Passthru2

Passthru3

Passthru4

They are all reachable from the Internet and have access to all the others Domino Servers in the cie.

I created a Cluster Group called Passthru_Cluster and added the above server in the cluster.

If I do a “SH Cluster” on every servers, everything is perfect… they are able to see each other.

On a Test Client, I have set the default Passthru Server in the Location document to PassThru1.

I have also created a passthru connection doc to his Home Mail Server via PassThru1.

This test user is using a modems and connect to the Internet via his ISP.

Here is what will happen:

If Passthru1 is available:

The test user will be able to get his mail.

If PassThru1 is not available, but All others are:

The Test user will get his mail and use one of the three passthru server that are still available.

If Two Passthru Server is not available:

Case1:

The client will receive an error about Passthru1 (Which is the default passthru Server)"PassThru1 is not available). The user will not be able to get his mail.

Case2: Sometime the user is able to get his mail threw one of the two remaining server.

If Three PassThru Server are not available:

The user is never able to get his mail threw the remaining passthru server who is a members of the cluster.

Why I’m not able to access the mailbox when the default passthru server is down as well as another random server ?
