Answer 1

This KB details which ports and protocols are used: http://support.microsoft.com/default.aspx?scid=kb;EN-US;178517

The following ports are used for Microsoft Message Queuing operations: TCP: 1801 RPC: 135, 2101*, 2103*, 2105* UDP: 3527, 1801 The following is new for Message Queuing 3.0:

While Message Queuing uses the same ports that are used in earlier versions of the product, Message Queuing also introduces TCP port 389. TCP port 389 has to be open for MQIS queries that are made directly against Active Directory. Additionally, Message Queuing 3.0 introduces HTTP Messaging that requires that the port that is specified for the Message Queuing virtual directory be open also.

This information is useful for interpreting the following: Netstat -a output A network trace Configuring a firewall

The currently accepted answer redirects to a link that is no longer available. The link has been superseded with a new support redesign.

https://learn.microsoft.com/en-us/troubleshoot/windows-server/networking/service-overview-and-network-port-requirements#message-queuing

Which provides documentation for all MSMQ from Windows 7 Service Pack 1 to Server 2019.

To not just provide an answer without meaningful information and to properly bring information here for the future admins who have to deal with this...

Application protocol	Protocol	Ports
MSMQ	TCP	1801
MSMQ	UDP	1801
MSMQ-DCs	TCP	2101
MSMQ-Mgmt	TCP	2107
MSMQ-Ping	UDP	3527
MSMQ-RPC	TCP	2105
MSMQ-RPC	TCP	2103
RPC	TCP	135

May it serve you well
