Rhp Design Manager integration with DOORS classic via Citrix?

Hi all,

I have a customer who wants to integrate DOORS classic with Rhp Design Manager.
The special thing is that DOORS client/server is accessed via Citrix (installed on remote system, outside customer network). DM will be installed on customer network.

Is it possible to integrate DM and DOORS on this scenario?
If possible, what are the considerations to take into account for connecting repositories and establish traceability?

Many thanks for you help.

Best Regards,
Paco
