TeamSound uses the following port configuration and negotiation process. NOTE: These port values are only valid for TeamSound 4.0 or later. a) the initial TCP connection and TCP data packets are sent from the TS client to the TS server on TCP port 40000. This can be adjusted using the /CTCP= command line switch on the client and the server. b) subsequent TCP data packets are sent from the TS server to the TS client on TCP port 40001. This can be adjusted using the /CTCP= command line switch on the client and the server. This is translated as the CTCP value plus one. c) outbound audio packets are sent from the TS client to the TS server on UDP port 40011 for the first user, incrementing one UDP port for each connected user. This can be adjusted using the /SUDP= command line switch on the client and the server. d) inbound audio packets are sent from the TS server to the TS client on UDP port 40002, 40003 and 40004 depending upon the preferences of the TS client.
