LMS 3.1 - TCP ports for Client to Server w/ regards to Topology Services

In LMS 3.1, I've had some difficulty opening Topology Services on client machines until I've opened the following ports on the server firewall, in addition to those provided by the documentation:

TCP 42342

TCP 43242

Is there some documentation which details what these ports are used for?

Also, I've seen multiple attempts in the firewall log from client machines to connect to tcp/1101 during usage of Topology Services, however it doesn't seem to affect usage. Does this port need to be opened as well?

Re: LMS 3.1 - TCP ports for Client to Server w/ regards to Topol

I have taken care of this internally in bug CSCsu02203. The LMS installtion guide has been updated on . The port that must be open between client and server for Topology Services to work is udp/42342.
