Overcoming firewalls in the cable modem with built-in router
There may be firewall options built in the integrated cable modem cum router that may block certain network
traffic and may interfere with the use of Digital Voice Global. If you experience problems with your Digital
Voice Global service and are connecting through a firewall, please perform the following steps to enable UDP
ports to and from the IAD:
1.
Disable Firewall on the integrated cable modem cum router
No additional settings is needed on IAD and cable modem with built-in router to use
Digital Voice Global
2.
When Firewall is enabled on the integrated cable modem cum router, there are 2 options available
as follows:
•
Configure “Port Forwarding” for the cable modem with built-in router on Port 5060/5061 and
16384-32767
Refer to Appendix 1 for setting of Port Forwarding. Please also ensure that the firewall policy on the cable modem with
built-in router allow the Port specified above. (See Appendix 2: Setting up the firewall for the SBG1000). For Wireless
Cable Gateway 200 cable modem with built-in router, Port Forwarding is not required on the Wireless Cable Gateway
200 even though the firewall is enabled.

the router.
