Chapter6. Basic Configuration
Onyour firewall, you need to open the SIP port (normally UDP port 5060) and a range of UDP ports for RTP traffic
betweenthe Telecommuting Module and the Internet. The other interface is connected to your internal network.
TheTelecommuting Module can handle several networks on the internal interface even if they are hidden behind
routers.No networks on other interfaces on the firewall can be handled.
Internalusers have to configure the Telecommuting Module as outbound proxy, or an internal proxy has to use the
TelecommutingModule as outbound proxy.
TheTelecommuting Module derives information about your network topology from the interface configuration.
The Standalone Configuration
Usingthis configuration, the Telecommuting Module is connected to your internal network on one interface and the
outsideworld on the other.
Usethis configuration only if your firewall lacks a DMZ interface, or for some other reason cannot be configured
forthe DMZ or DMZ/LAN alternatives.
Internalusers have to configure the Telecommuting Module as outbound proxy, or an internal proxy has to use the
TelecommutingModule as outbound proxy. No change in the firewall configuration is needed.
TheTelecommuting Module derives information about your network topology from the interface configuration.
