    Hi olig,

     

    Since your VoIP provider has suggested it then it means that it might help for the VoIP solution to function well.  Try to follow the suggestion then observe what happens.  If ever it doesn't help then you may just delete the rules then inform your VoIP provider about it.

Hi DaneA

 

Thanks for the prompt reply.

 

  1. The setup is very simple and straightforward: Internet signal coming through a modem/router to WAN1 of the Netgear FVS336G. From there LAN1 goes to a Smart Switch which leads to the different workstations and IP phones. IP address to the outside world is fix.

  2. I’m afraid there hasn’t been an update for quite a while. Firmware – Version: 3.0.6-28

  3. The VoIP provider initially gave me the following information:

IP range for communication WAN/LAN and LAN/WAN

Where do I configure this?

UDP Ports

Done

IP range for configuration LAN/WAN for http:// and http://

Where do I configure this?

TCP ports WAN to LAN and LAN to WAN

Where do I configure this?

 

                          

Forgive my ignorance, but would these parameters set correctly already limit the SIP signals to only come from the provider, or do we need additional settings?

 

Thanks and regards

Oliver

Hi olig,

 

I think you could configure the IP range on the Firewall LAN WAN rules.  Kindly refer to the figure on page 230 of the FVS336Gv2 reference manual here.  As you can observe, you can select IP Range on "Send to LAN Server."
