Level
Description
Standard
No firewall is applied on the Talk2m server.
The connected users have access to all devices on the LAN, to the Ewon gateway and to the Ewon itself.
High
The Talk2m firewall is applied on the LAN-Devices. Only the declared LAN devices are accessible on specified ports.
The Ewon itself and its gateways remains unfirewalled, so accessible by connected users
Enforced
The Talk2m firewall is applied on the LAN-Devices and on Ewon gateways.
Only the declared LAN devices and the declared gateways are accessible.
The Ewon itself remains unfirewalled, so accessible by connected users.
Ultra
Same as Enforced, but the access to the Ewon itself will also be firewalled.
So only specified Services of the Ewon (HTTP, SNMP, etc.) can be accessed.
Padlock Firewall Level representation:
The padlocks reflect the Firewall Settings applied on the Gateway and LAN level:
A closed padlock signifies that the access is firewalled. Only declared devices, ports and/or gateways are accessible.
An open padlock indicates that no firewall is applied.
The padlock will also be displayed inside the Active Connection window of Ecatcher, so the user can directly see which firewall settings are applied on this Ewon.
LAN Device
Defining the accessible LAN devices behind an Ewon is necessary for limiting access to the LAN network (machine network) and for making devices visible in M2web.
To add a LAN device to an Ewon:
Select the Ewon from the Ewon list and click on Properties.
In the LAN & Firewall section, click on Configure LAN devices & Firewall.... The Devices & Firewall window opens:
Click on Add LAN device... to open the LAN Device settings.
Give a name to your LAN device, specify its IP address and optionally write a description.
For the Port field select All Protocols if they are all open or Specific-Protocol if a specific port must remain open.
Notice
To limit the access to a specific protocol, select the protocol you want to allow on the device inside the Specific Protocol list.
For example, ISO TCP (Siemens) or EIP (Rockwell).
You can also define custom ports using following syntax:
T405 => TCP port 405
U9600 => UDP port 9600
T443,U1194 => TCP port 443 & UDP port 1194
In the option Visible in M2web; you can define whether the device will be visible or not using M2web access.
Depending on the configuration, the Visible in M2web will ask for details about:
- The protocol to use for this device (4 options: HTTP, HTTPS, VNC or RDP)
- The home page or URL that will be used when clicking on the device's name in M2web. The URL can contain anchors and/or arguments. This field is optional.
Notice
On a Talk2m pro account you can also restrict the access to a specific user group.
Warning
On a free or light account this restriction is not available. All declared users of the account will have access to the device.
When the information is encoded, the Firewall slider is automatically shifted to position High since it is the position required to activate the firewall protection at the LAN side.
The new LAN device appears with a closed padlock under the structure of the relevant Ewon:
The firewall level can be manually moved back to Standard if you do not want to activate the firewall protection.
PLC Discovery:
The LAN Device section is also the place to configure the PLC Discovery.
The PLC discovery feature allows PLC connection software to automatically detect devices on the Ewon's LAN network when you are connected to the Ewon through Ecatcher.
Notice
This feature is available on the Ewon beginning with firmware v12.
By default, the PLC Discovery feature is activated in Ecatcher.
When the firewall is set on Standard, the feature will not be displayed.
If it is changed to High, Enforced or Ultra, a new option line will appear underneath the LAN heading and will allow you to disable it.
Tip
For more information about the PLC Discovery on the Ewon, please refer to the AUG-070: PLC Discovery through Talk2m.

Mail and SMS relay
The Talk2m Email/SMS Relay helps you send emails and SMS text messages from any Ewon connected to Talk2m, and is available for all Talk2m accounts.
All you need in order to use the Talk2m relay is:
a valid Talk2m account
a SMTP server address in the Ewon settings that links to "relay.talk2m.com" (even if you only want to send SMS)
Tip
If you need explanations on how to configure the SMTP server address and how to send emails and SMS message, please refer to our SSH-0046-00 - Email and Text Messages (SMS) relay using Talk2m on the support website.
The Benefits of such process:
It is not necessary to know the SMTP-server of the local Internet connection which enables you to use the same settings in all your Ewons.
No need to have an Ewon with wireless modem to send out text messages (SMS)
For Ewons having a wireless modem, the action of sending out an SMS does not interrupt the Internet connection.
It allows sending emails and SMS through a Proxy server
There is no risk that the access to the SMTP server is blocked by the local Internet connection
You have a greater security due to the VPN encryption
You will find more information about the Mail and SMS relay on our support website.
