In general, for the majority of intercomponent communications across the network, Client Automation only requires two ports to be opened, specifically UDP port 4104 for (typically light) message-based traffic and TCP port 4728 for (typically bulk) stream traffic.
By default, remote communications through CA Message Queuing (CAM) will use UDP over port 4104, as documented in the following tables. You can configure CAM to use TCP for remote communications (in some circumstances this can be preferable), in which case TCP with a source port of ANY and a listening port of 4105 will be used. If SSA is installed on the local machine, CAM TCP port communication would be port multiplexed through SSA port 7163 for all outbound connections by default. Remote communications through CAM over TCP is not documented in the tables. CAM is also used extensively for local communications, that is, between components running on the same machine. In this case, TCP on port 4105 is used.
Certain features within Client Automation can use file shares if configured to do so. In this case, appropriate file share ports must be opened. Specific port numbers will vary depending on the operating environment (platform) and the mechanisms available and configured.
Typical file share ports are as follows:
Either 139/TCP (old style) or 445/TCP (new style)
2049/TCP (NFS)
