3.8 Network security
3.8.1 Access control
In this menu, you can limit the access to the web interface. You can use either the blacklist or whitelist
principle. When the blacklist principle is used, all devices are granted access. Simultaneously, access is
prohibited for the devices on the list. When the whitelist principle is used, access is prohibited for all devices.
However, devices that are on the list are granted access.
In this menu you can also determine the period of time after which an automatic logout from the web
interface should be performed after no entries are detected from the user any more.
3.8.2 E-mail alarm
The PROmesh P20 has several alarm options. Here you can determine the alarm receiver for the alarm
sent by e-mail. To this end, the following settings have to be configured:
User/Login/E-mail address
: Enter the account name of the e-mail address.
Authentication password
: Enter the password for the e-mail address via which you want to send
the alarms.
Send e-mail address
: Enter an e-mail from which the alarms are to be sent.
Receive e-mail address
: Enter an e-mail to which the alarms are to be sent.
SMTP Server
: Enter the address of your SMTP server for the sender e-mail address.
Port
: If necessary, you can configure the port via which the message is sent here.
3.9 NAT configuration
The Network Address Translation (NAT) is a procedure for changing IP addresses in IPv4 packages. Thus
you can enable communication between two networks whose devices normally cannot interact. It is also
possible to separate an existing network. For this, the higher-level network has to be connected to the Layer
3 port of the switch. The default port for this is
Port 20
. You can connect devices for the internal network to
the other 19 ports. With the NAT function, you can specifically define which devices of your internal network
are permitted to communicate with the devices of the external (higher-level) network.
3.9.1 NAT configuration rules
In this menu, you can define Network Access Translation rules. To create a NAT rule, the following entries
have to be made:
Name
: Enter a name for the NAT rule.
Mode
: Here you can determine whether the rule only applies for UDP, only for TCP, or for all
protocols.
