8.3 Diagnostic page
In the event of irregularities or interruptions when establishing the connection, the diagnostics page
supports you with troubleshooting. In the event of an error, the technical support of Helmholz requires
the respective result from the individual and autonomous test functions.
8.4 Is a MAC address filter activated in the firewall? (relevant for internet access via
P1 WAN interface)
It may be necessary to approve the MAC address of the REX 200/250 in the higher-level DSL modem or
firewall. Should it not be possible to establish a connection, please ask the respective network administra-
tor whether such a MAC address filter has been activated.
8.5 Is the connection established over a proxy? (relevant for internet access via P1
WAN interface)
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
200/250 in the Internet settings.
