How can I open the ports 10k-20k and 5060 for sip phones using RV220w?

Also, need to open traffic to sip provider's ip address.

Thanks

Hello, 

In order to answer your question correctly I need answer to the following questions:

1- Are you trying to open the ports to a PBX or phones?

2- If phones, how many?

3- about this statement: need to open traffic to sip provider's ip address. What kind of traffic? Going where?

I will give you an answer to your questions once I receive your reply.

Hello and thank you for your reply.

Unfortunately I don't have good news. What you are intending to do is just not possible. You can only open a port to a single device on the network, not to many.

In this situation the router offers a feature that may help.

On the RV220W go to Firewall, then Advance Settings and enable SIP ALG.

From the RV220W help page:

SIP ALG

Session Initiation Protocol Application-Level Gateway (SIP ALG) can rewrite information within SIP messages (SIP headers and SDP body) to allow signaling and audio traffic between a client on your private network and a SIP endpoint.

Usually enabling this feature works, hopefully it will be the same for you, besides this there is nothing else that can be done on the device to pass all those ports to the inside of the network to multiple devices.

2 thoughts.

should I just use port triggering?

1. Port triggering is a configuration option on a NAT-enabled router that allows a host machine to dynamically and automatically forward a specific port back to itself. Port triggering opens an incoming portwhen your computer is using a specified outgoing port for specific traffic.

I am just losing packets while on calls.

Hello,

That was a good idea, but it will not work. Remember, port triggering is just a dynamic way of doing port forwarding, but at the end of the day you will be trying to forward the same ports to different devices on the network which is just not possible.

Maybe you could get a single PBX on site to which the phones will register to? That way we can forward all the needed ports just to the PBX and this one will be the one registering over the internet.

I hope this helps
