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.

Port forwarding
You can use port forwarding, also called port mapping, to avoid port conflicts and port restrictions within your Code42 environment and on other networks.

Port(s)	Protocol	Source	Destination	Description
4282	TCP	LAN networks Internet	Your Master server	Backup and sync traffic from internal and external endpoints Statistics and job status from internal and external endpoints
4282	TCP	LAN networks Internet	Your Storage servers	Backup and sync traffic from internal and external endpoints
4280 (http) 4285 (https)	TCP	LAN networks Internet	Your Enterprise server	Access for administration console and web restore to internal and external endpoints

Outbound ports

Specific ips
For specific IPs, sign in with a privileged account or contact our Customer Champions for CrashPlan PROe support or CrashPlan for Small Business (previously CrashPlan PRO) support.

4286	TCP	Your Enterprise server	Your Enterprise server	Statistics traffic between enterprise servers*

*On Windows enterprise servers, this port must be enabled for both Public and Private networks.

CrashPlan app ports

Port(s)	Protocol	Source	Destination	Description
4282	TCP	LAN networks	Your Enterprise server(s)	(Default) Communication from the device to enterprise server(s) in private cloud environments
443	TCP	LAN networks	Code42 cloud	Communication from the device to the Code42 cloud
4243*	TCP	Localhost	Localhost	(Default) CrashPlan app connecting to CrashPlan service
4242*	TCP	CrashPlan Device	CrashPlan Device	(Default) Computer-to-computer backups in CrashPlan PROe
1,024 - 14500, 49,000 - 52,000	TCP	CrashPlan Device	CrashPlan Device	(Optional) NAT traversal ranges used for connecting between computers

5351	UDP	CrashPlan Device	CrashPlan Device	(Optional) Standard NAT-PMP port required for computer-to-computer connections

* CrashPlan version 4.3 and later will use a different pair of available ports if the default ports are in use. The ports in use by the CrashPlan service can be found in the app.log file.

SharePlan App ports

443 4282	TCP	LAN networks	Your Enterprise server	Sync traffic from internal endpoints to enterprise server.
4252	TCP	LAN networks	LAN networks	SharePlan app sync traffic directly between internal endpoints

Monitoring ports

Only apply firewall rules for monitoring if you use Code42's managed appliance monitoring.

Specific ips
For specific IPs, sign in with a privileged account or contact our Customer Champions for CrashPlan PROe support or CrashPlan for Small Business support.
