TCP and UDP ports used by the Code42 platform
Who is this article for?
Code42 for Enterprise, yes.
CrashPlan for Small Business, no.
This article applies to on-premises authority server version 4.
Note: This server version is no longer supported.
Overview
CrashPlan PROe, the CrashPlan app, the SharePlan app, and other products in your Code42 environment use certain network ports to function normally. If you have network connectivity issues with CrashPlan PROe, verify that your firewall rules permit traffic over these ports.
Enterprise Server network ports
Inbound ports
The following table lists the default enterprise server ports. It is best practice to deny inbound traffic at the firewall for any ports not needed by the Code42 configuration.
You can use port forwarding, also called port mapping, to avoid port conflicts and port restrictions within your Code42 environment and on other networks.
