Firewall
The system must be accessible via the Internet to allow printing, the following table contains the required open ports for the respective components:
| Source System | Source | Port | Target System | Target | Target Port | Protocol |
| Mobile Devices | Internet | 8443 | Load Balancer | Internet | 8443 | IPPS |
| Load Balancer | Internet | 8443 | Print Proxy | DMZ | 8443 | IPPS |
| Print Proxy | DMZ | 8631 | Print Server | DMZ | 8631 | IPP |
| Print Server | DMZ | 515 | Printserver Solution | Intranet | 515 | LPD |
| Print Proxy | DMZ | 443 | EMM System (API-Component) | DMZ | 443 | HTTPS |
| Print Proxy | DMZ | 8443 | Print Proxy Admin Portal | Intranet | 8443 | HTTPS |
Appliance
The solution can be installed using an appliance. EBF provides ISO images used to carry out the application installation and can be provided by EBF for download over the Internet. Alternatively, installation into an existing systems can be achieved with a JAR file installation provided on request at EBF.
The appliances are usually virtual machines (from VMware or other VM providers) and are based on CentOS 7 x64 Linux distribution.
The following specifications for the virtual machines are recommended:
| Hardware | Recommendation |
| CPU | min. 4 Cores |
| RAM | min. 4GB (8GB if on one machine) |
| HDD | min. 50GB |
A high availability (HA) solution can be achieved by integrating a load balancer with round-robin load distribution within the active proxies and the downstream print server systems.
Secured Connection
Certificate
To secure communication appropriate SSL certificates are required, ideally issued to the server names and in an iOS-compatible format. Depending on the implementation, these certificates must be stored directly in the server systems or on the load balancer system (SSL offloading)
Requirements for trusted certificates in iOS 13 and macOS 10.15
