DHCP Settings
Your network has to be configured to automatically assign an IPv4 address to your device (DHCP). Assigning a static IP on the machine directly by yourself, our partners or LYMB.iO is unfortunately not possible.
Firewall Settings
Besides the physical connection to the internet, it's essential to have the required ports open for outbound only connections and allow access to a set of domains.
The client's security impact is minimal as long as these ports remain closed for inbound traffic and other devices.
Ports & Domains
Please tell your IT department to open the following ports for outbound traffic only. These are needed for normal usage, including software updates (these are open usually anyways as they are pretty standard):
| Port | Type | Direction | Destination | Service |
| 53 | UDP TCP |
outbound | 8.8.8.8 8.8.4.4 |
DNS |
| 123 | UDP TCP |
outbound | ntp.ubuntu.com | NTP |
| 80 | TCP | outbound | *.ubuntu.com *.s3.amazonaws.com |
HTTP |
| 443 | TCP | outbound | *.multiball-admin.net *.courtadmin.net *.lymb-admin.net *.s3.amazonaws.com *.ubuntu.com |
HTTPS |
The following additional ports we recommend to be usable in case for service access is needed when you encounter problems and need remote help from us, or when old software needs to be updated one last time like mentioned above:
| Port | Type | Direction | Destination | Service |
| 22 | TCP | outbound | tunnel.courtadmin.net (3.64.218.58) | SSH |
| 1194 | UDP | outbound | vpn.courtadmin.net (52.59.113.67) | VPN |
SSL Interception
Please do not use any firewall that uses SSL interception, since you are not able to change the Certificate Authority on the system.
MAC Address
Your IT department may need the system's MAC address before they can allow the system any internet access. You will find the addresses of both ports in your admin page under Systems > Settings > Network
WiFi
Neither MultiBall nor interactiveSQUASH includes a wireless network adapter. However, you can still connect them to WiFi using a separate LAN to WiFi device (such as a bridge or repeater with a LAN port). Place the device near your MultiBall or interactiveSQUASH and connect your system to it using a LAN cable.
Please note that this device is not included and must be purchased separately by the customer. Your local network specialist can assist you with setting this up.
Internet Speed and Traffic Limits
To ensure your system updates quickly and reliably, we recommend having a minimum download speed of 20 Mbps and a minimum upload speed of 5 Mbps. It's also advisable to opt for an unlimited contract to avoid traffic limits.
