Replicating with clustered servers via clustered passthru-servers

Challenge:==========

To get a server in a branchoffice to replicate (over WAN) with clustered servers in HQ through clustered Passthru

servers, using only one single connection document utilizing the cluster-names of the HQ-based servers ?

Platform:

=========

Windows 2008 R2.

Lotus Domino v8.5.3 FP1

Scenario:

==========

Sample Domino Domain: “Company”, all servers in same Domain, same Domino Directory, but ServerA in different NNN.

Sample servernames:

===================

ServerA/EXT/Company Somewhere in the world, NOT same NNN as the rest of the servers!

ServerB1/DMZ/Company In DMZ at HQ, clustered with ServerB2 in cluster “ClusterB”.

ServerB2/DMZ/Company In DMZ at HQ, clustered with ServerB1 in cluster “ClusterB”.

ServerC1/Company On the LAN at HQ, clustered with Serverc2 in cluster “ClusterC”.

ServerC2/Company On the LAN at HQ, clustered with Serverc1 in cluster “ClusterC”.

DNS:

====

serverb1.company.no

serverb2.company.no

FQIHN:

======

ServerA: serverA.company.local

ServerB1: serverB1.company.no

ServerB2: serverB2.company.no

ServerC1: serverC1.company.int

ServerC2: ServerC2.company.int

ServerA should replicate with servers in ClusterC using passthru connection via servers in ClusterB.

Since ServerC1 and ServerC2 are on LAN they are accessed passing through ServerB1 and ServerB2 which are

exposed in DMZ and are set up with Public IPs.

I thought I would create the connection document like this:

Source server: ServerA/EXT/Company

Destination server: ClusterC

Use passthru server…: ClusterB

…and that ServerA would attempt cluster-replication with server(s) ServerC1 or ServerC2 by attempting to

reach either of the two servers in ClusterB by using the Fully Qualified Internet Host name listed in the

server doc of those two servers (serverb1.company.no, serverb2.company.no).

Thus all I would need was one connection doc from ServerA to Servers in clusterC specifying to go via servers

in ClusterB ?

Does anybody have experience with this ?

I cannot find the right way of setting up the connection doc. to get it to work without explicitely naming

the servers involved - and that kind of destroys the whole concept of the “talking to/via clusters” thing ?

Where to use the Cluster-names or where to just use the explicit name of one of the clustered servers

(and then Domino will arrange the rest ?)

I have it working but I had to add four connection documents which I think should not be required:

I had to add a connection document between

ServerA and ServerC1 using passthruserver ServerB1

ServerA and ServerC1 using passthruserver ServerB2

ServerA and ServerC2 using passthruserver ServerB1

ServerA and ServerC2 using passthruserver ServerB2

(All of these have replication and mailrouting disabled.)

When doing so, my orignal single connection document idea works, but really it should have even without these

four additional connection documents ?

Does this mean I cannot use the clustername for the passthru servers ?
