IPF-2002L User Manual

7. Passing through the NAT/Firewall:

When IPF-2002L works with NAT/Firewall, some of the following cases might happen:

1.With a valid account, IPF-2002L can not successfully register to the server.

2.IPF-2002L itself can make calls but is not able to receive calls.

3.One-way talk. One end can not hear any sound.

It might be the NAT/Firewall issues in these cases. IPF-2002L supports two methods to allow SIP passing through the NAT/Firewall by deploying STUN or Outbound Proxy.

7.1SIP with STUN

•service address: fill up the IP address or domain name of the SIP Proxy server.

•nat traversal: select STUN from the drop down list.

•nat addr: fill up the IP address and domain name of the STUN server.

7.2SIP with Outbound Proxy

•service address: fill up the IP address or domain name of the Outbound Proxy server. If the port of the Outbound Proxy is not 5060, please add “:” and the port number right after the IP address.

•service id: fill up the IP address or domain name of the SIP Proxy server.

•nat traversal: select disable.
