8.5 Is the connection established over a proxy?  

If a connection is not established on the customer network, the required proxy settings may not have  

been stored or may be faulty. These settings may be adjusted on the configuration page of the REX 100 in  

the Internet settings.  

8.6 Device configuration: Services – NTP server  

For the internal system time of the REX 100, this carries out a comparison using a time server on the In-  

ternet at regular intervals. Where necessary, you can individually set the preset NTP server entry and the  

interval.  

Various functions in the myREX24 portal require a current time setting in the REX 100.  

8.7 Device configuration: Services – Mail settings  

If you would like to use the REX 100 function for the automatic sending of e-mails, port 25 (SMTP) may  

not be blocked in the firewall of the customer network. You can also use alternative e-mail servers to send  

e-mails.  

8.8 Mobile connection is interrupted  

If the provider for mobile communication remote maintenance interrupts the connection of your REX  

100 router, this may have occurred for the following reasons, among others:  

- Wrong username/ password  

- Ports blocked by the provider  

- Credit of prepaid SIM cards used up
