- 80/443 (TCP) Requires both incoming and outgoing access so that the Retain Server and the Message Router can communicate device configuration information with each other. See also the Retain Message Router component in this article as well as the Mobile subsection under Retain Worker. See also the Retain Message Router component in this article
- 111/2049 (UDP / TCP) for NFS Server services Requires incoming access if the Worker is not on the Message Router server so that the Message Router can place the logs on the Worker's server. Samba can be used, but NFS seems to be more reliable
It is up to the customer to do this research to get NFS services to work properly.
