Setting up the network

Internet Settings

Priority	Port	Protocol	Name of the protocol	Description
required	123	UDP	NTP	Access to the time server that the DHCP server provides. Without NTP, secure connections cannot be established because certificates cannot be validated.
required	53	UDP	DNS	Domain Name Service – name resolution on the Internet. With this protocol, Internet addresses (e.g. .tapio.one) are resolved into IP addresses.
required	443	TCP	HTTPS	Encrypted connection to the Internet. Required to connect the tapio cloud and the HOMAG cloud services.
optional	13	ICMP	ICMP	Outbound pings are required to verify the connection to the cloud services.

^*Optional: These ports are not required for the operation of the sR Bridge and are used for diagnostics and analysis in the event of support cases.

Settings for the internal network

The sR Bridge has various diagnostic services that should be accessible in the local network. We recommend that you make these services available only on the internal network.

Priority	Port	Protocol	Name of the protocol	Description
required	80	TCP	HTTP	Local diagnostic page of the sR Bridge.
required	37001	TCP/UDP		Discovery service for the device pairing process. Communication between the machines and the sR Bridge.
optional*	5353	UDP	mDNS	Multicast DNS service to provide the SR Bridge name on the local network.
optional*	5355	UDP	LLMNR	Link-Local Multicast Name Resolution; allows hosts to perform name resolution for devices on the same LAN.
optional*	13	ICMP	ICMP	Incoming pings to check if the sR Bridge is online - Attention: Only one ping per second is allowed!
optional	22	TCP	SSH	The SSH service is disabled by default and must be enabled manually through the Diagnostic Web Interface. In the case of local maintenance or remote maintenance, the service employee can activate the function manually. When the SSH service is enabled, the status is displayed in the diagnostic pages and via the status light.

^*optional: These ports are not required for the operation of the sR Bridge and are used for diagnostics and analysis in the event of support cases.

Settings for the sR Bridge network

You can adjust the network settings of your sR Bridge via the CUBE-diagnose-im-lokalen-netzwerk" target="_blank">local diagnostics page . A manual adjustment of the settings is necessary if you want to set special IP settings for the sR Bridge in your network. By default, the sR Bridge receives the required network configurations from your Internet router via DHCP.

NOTE: If DHCP is disabled on the network, accessing the device interface is complicated. It is advisable to temporarily activate the DHCP for commissioning. For more information, see the Troubleshooting chapter in the manual or in the FAQs.

For more information, see the Local Network Diagnostics page.

We recommend using the default configuration via DHCP. In the event of a misconfiguration, the function of the sR Bridge is no longer guaranteed.

In a current Internet browser, enter the host ID, or if known, the IP address, in the address bar and press Enter. Now log in to the device interface with the device password. The host ID and password can be found on the label on the back of the sR Bridge or on the enclosed additional label.

On the diagnostics page, you have the following setting options:

Hostname: Change the hostname of the sR Bridge

The hostname of the CUBE is composed according to the following pattern: homag-iot-<mac address>
You can access the sR Bridge from the sR Bridge hostname (without knowing the IP address) on the local diagnostics page, which is useful if you have Internet problems setting up the sR Bridge, for example. The local diagnostics page will help you with this.
NOTE: If you have configured a domain on your network, please use the following scheme to access the local diagnostics page: <hostname>.<domain>

DNS: Configuring the name server for the sR Bridge

The name server is used to resolve the hostname to an IP address. In small networks, this is often the Internet router. For larger networks, a separate DNS server is often operated.

Default Gateway

The default gateway is a node in your network through which sR Bridge finds its way to the Internet. By default, this is your Internet router.

NTP Server: Time Server

If you have your own time server in your network, you can configure it here. Some DHCP servers come with this automatically, so you don't have to do any configuration. If you do not have an NTP server in your network, please make sure in your firewall that the sR Bridge can access one of the following default servers via the NTP protocol.
- time1.google.com
- time2.google.com
- time3.google.com
- time4.google.com
- time.windows.com

DHCP / Static Network Settings

The "Enable DHCP client" selector allows you to specify whether your sR Bridge should receive the network configuration from a DHCP server or a static network configuration.
ATTENTION: We recommend that you use the default configuration via DHCP. In the event of a misconfiguration, the function of the sR Bridge is no longer given. However, you can return to the default configuration via the factory settings.

Only by pressing the "Save and activate" button will the network settings be applied after confirming a dialog.

Note:
The settings for the LAN 2 network adapter must not be changed.
