1. ntp.pool.org should be resolved to an address within the internet. The device attempts to reach this
destination through the default gateway 10.0.0.1 at the 1st interface.
2. Destination 10.0.0.2 is within the local net of the 1st interface. Therefore it could be reached directly.
3. Destination 192.168.1.3 is within the local net of the 2nd interface. Therefore it could be reached
directly.
4. Destination 192.168.47.11 is not within any of the two local networks. But it could be reached through
the router 192.168.1.1 of the 2nd interface.
9.4.3 Device SSH Settings
The dialog box allows displaying and entering the SSH parameters (Secure Shell, network protocol
for encrypted connections).
SSH allows you to establish an encrypted VPN connection to the device via the Internet. It also offers
the possibility to reach the device through a firewall, usually via TCP/IP port 22.
In this way, you can access a connected PLC or parameterize the device.
SSH Base Settings
Use SSH
Enables access using SSH.
SSH Port
Port number at which the device is accessed via the SSH connection.
Encryption Bits
Specifies the number of bits used for encryption. Normally 1024 bits are used.
The following rule applies: The higher the number of bits, the more secure the connection – and the
slower the line speed. The default value of 1024 suits most purposes.
SSH User Accounts

At least one user and one password have to be entered here. The minimum length of the password is
6 characters.
