Ewon Cloud Onsite Firewall Requirements
The section provides customers with the Ewon Cloud servers information: their host name and their IP address.
Endpoints for Ewon Edge devices are based on an architecture that consists of multiple interconnected servers and services.
The simplest solution is to whitelist the following wildcard domains:
*.ewoncloud.com for outgoing port TCP 443 and UDP 123
*.amazonaws.com for outgoing port TCP 443
*.talk2m.com for outgoing port TCP 443 or UDP 1194
If your firewall does not support wildcard domains, refer to the information below for a detailed list of the required domain names:
HTTPS Endpoints for Ewon Edge Gateways
Allowing these addresses is mandatory.
Host Name | Port |
|---|---|
mqtt.iot.eu1.ewoncloud.com (Note: Firmware before 2.3.1 used a2sc4syryh4uzp-ats.iot.eu-central-1.amazonaws.com) | TCP 443 |
c2hfwgug9m20rj.credentials.iot.eu-central-1.amazonaws.com | TCP 443 |
hms-device-firmware-binaries-prod-423s1.s3.amazonaws.com | TCP 443 |
hms-device-firmware-binaries-prod-423s1.s3.eu-central-1.amazonaws.com | TCP 443 |
ewoncloud-gateway-storage-prod-20250908135320979000000001.s3.amazonaws.com | TCP 443 |
ewoncloud-gateway-storage-prod-20250908135320979000000001.s3.eu-central-1.amazonaws.com | TCP 443 |
Warning
The IP addresses used by our servers are dynamically assigned by Amazon Web Services (AWS) and may change at any time. Therefore, we do not recommend relying on fixed IP addresses in firewall rules. Should you need the IP addresses used by our services, run a DNS lookup using the nslookup command from a Command Prompt. This will return the IP addresses currently assigned to our servers.
NTP Endpoints for Ewon Edge Gateways
Allowing these addresses is recommended.
Host Name | Port |
|---|---|
ntp.ewoncloud.com | UDP 123 |
Note
By default, the Ewon uses this NTP server for time synchronization. You can configure a different NTP server in the device settings.
If a custom NTP server must be used during the initial configuration, the Internet connection will likely need to be configured locally using the secure USB configuration method with a USB key.
VPN Endpoints for Ewon Devices
Tip
Recommendations for Internet access rules:
For outbound connections on port TCP 443 (HTTPS), our customers should whitelist the entire Talk2m domain (hostname: *.talk2m.com).
This will ensure that services remain uninterrupted in the event of maintenance or load balancing. We also suggest whitelisting the Talk2m domain for outbound connections on port UDP 1194.
If it is not possible to do for you, then you can find below the list of endpoints to whitelist manually.
Find and allow the IP addresses used by your Ewons. If you don't know which VPN server your Ewon is linked to, please refer to the Talk2m Connection Checker section here above.
Whitelist the backup server as it will be used in case we must switch the Ewon devices because of a "primary" server failure.
Backup servers in USA, Europe and China are the other servers within the same region list.
