Enter the IP addresses of the device you wish to forward ports for (in this case, your VoIP phones). While these headers often indicate an attack on your Firebox, you can disable this option if necessary for your VoIP solution to operate correctly. (Some routers, may have SIP ALG enabled by default, but not have an option to disable within the web interface.) Below we have provided related information for several common device manufacturers.
