Code42 Support

IP addresses and ports used by the Code42 platform

Overview

The Code42 server, the Code42 app, and other products in your Code42 environment use certain network ports to function normally. If you have network connectivity issues with Code42 for Enterprise, verify that your firewall rules permit traffic over these ports.

Open only the necessary ports
As a best practice, configure firewalls to open only those ports required by your software.
Deny inbound traffic at all other ports.

Code42 server network ports

The following tables list the default Code42 server ports.

Inbound ports

In firewalls:

  • Open port 4287 for inbound requests from Code42 apps.
  • Open port 4285 for inbound requests from browsers and from Code42 apps version 6.5 and later.
  • Open 4282 and 4280 only in the rare cases where your server does not use TLS security.
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

4287 (TLS)

  • LAN networks
  • Internet

Your authority server and storage servers
  • Browser access to administration consoles, and to web restore to internal and external endpoints
  • For Code42 servers 6.5 and later deploying Code42 apps 6.5 and later, access for client deployment and customization.

Outbound ports

In firewalls:

  • Open ports 25, 53, 123, and 443 to let your Code42 servers send requests to mail, DNS, NTP (Network Time Protocol) servers, and the Code42 license server.
  • Open an LDAP or RADIUS port only if you use one of those services.
  • Open port 5432 only for a server that uses a PostgreSQL database.
    • Open 5432 if PostgreSQL resides at an IP address other than the server's address,
    • Or open 5432 if PostgreSQL and your server share the same address, but your firewall otherwise blocks connections to localhost.

Multi-server deployment ports

If you use multiple Code42 servers, most likely one authority server and one or more storage servers, then in the firewall that protects each server:

  • Open port 4288 both inbound and outbound, for server-to-server communications.
  • Open port 4286, both inbound and outbound, also for server-to-server communications.
  • Open 4283 only in the rare cases where your servers do not use TLS security.
Port(s) Protocol Source Destination Description

4288 (TLS)

Your Code42 server Data balancing between Code42 servers
4286 TCP

Code42 app ports

Code42 apps use two or four outbound ports. In firewalls that protect your devices and the LANs where they reside:

  • Open 4287 for outbound messages to your authority server.
    • Open 4282 only in the rare case that your server does not use TLS security.
  • If you use Code42 cloud storage:
    • Open port 443 for outbound messages to storage server.
  • The Code42 app and the Code42 service run on the same device.
    Open port 4243 only if your firewall otherwise blocks connections from localhost to localhost.
    • If the default port 4243 is in use when the Code42 app installs, the app uses some other available port. See the app.log file
  • To enable the optional web restore function, open port 4285 for outbound messages from browsers to storage servers, on-premises or in the Code42 cloud.

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