Overview
SEP sesam client-server communication requires certain TCP ports to be open to enable SEP sesam components to communicate with each other through a firewall. Daemons are specific to the SEP sesam Client/SEP sesam Server/RDS installation and are using different port numbers.
The ports required may be SEP sesam version-specific. As of version ≥ 4.4.3 Beefalo, SEP sesam uses fewer ports per default than in the previous versions:
Ensure that all required ports are available on the system for SEP sesam daemons and that they are not blocked by a firewall; these ports may not be assigned to another service. If the required ports are not available, SEP sesam will not function correctly.
Additionally, you might need to open relevant network ports to ensure communication between SEP sesam Server or SEP sesam data mover and additional modules, e.g., VMware vSphere, NDMP, etc. For the list of module-related ports, see below section Module-related ports.
Used default ports in version ≥ 4.4.3 Beefalo
If a firewall is used, then only the following TCP ports must be allowed for SEP sesam backup in versions ≥ 4.4.3 Beefalo. SEP recommends SMSSH for secure control communication between SEP S
sesam Server and SEP sesam Clients/RDS and the HTTP protocol for data transfer from SEP sesam Client to the SEP sesam device server. SMSSH and HTTP are the default protocols, if no other protocol is specified in the client configuration and in the different events (backup/restore/migration etc.).

SEP sesam full ports list
The following is the full list of ports used by SEP sesam. You only need to open the ports in your firewall which you're using. If you decide to configure all control communications over SMSSH, you don't have to open the CTRL port 11301 in the firewall.

| 11701+drive number |
Replication and source-side deduplication (SDS) port |
For example:
- If you replicate from dedup drive 2 (source) to the RDS drive 5 (target), the port is 11703 (daemon on the machine with drive 2).
- If you replicate from dedup drive 5 (source) to the RDS drive 2 (target), the port is 11706 (daemon on the machine with drive 5).

GUI/WEB UI (RMI) listen port |

|
Note
|
| For external backups (BSR, SAP, Informix, MaxDB ...), the client must always be able to reach the SEP sesam Server via ports 11000 (for HTTP backups), 11443 (for HTTPS backups) and 11001 (for FTP backups), and not only the RDS. This must be taken into account in the firewall rules.
