•If you use a DMZ Telecommuting Module Type, check on the Surroundings page that you have separated the clients into correct networks. Clients that can reach each other without using the Telecommuting Module should be in the same Surroundings network, and clients that must use the Telecommuting Module to reach each other should be in different Surroundings networks.

•If you use a DMZ or DMZ/LAN Telecommuting Module Type, check that the firewall connected to the Telecommuting Module does not block the media. See the chapter titled Firewall and Client Configuration, for more information about which ports should be opened in the firewall.

•Check the log to see if your access attempts reached the Telecommuting Module.

•Check that the configuration IP address (Configuration Transport on the Access Control page) is the one you use when trying to access the Telecommuting Module. Note that if you apply a configuration which changes the configuration IP address, your web browser will not automatically be redirected to the new IP address.

•Check that configuration traffic is allowed via the interface your web browser is located behind (Configuration Allowed Via Interface on the Access Control page).

•Check that configuration traffic is allowed from the computer where you run your web browser (Configuration Computers on the Access Control page).
