Problem with Cisco IP Phone 7911

[vithort]

Hi guys,

Explaining the problem:

I have a network with pfSense within another network. What happens is that I have to make a phone "Cisco IP Phone 7911" to have an IP network from outside the pfSense.
My pfsense network (192.168.4.0/20) is where the Cisco phone. The other network is a private segment (10.xx.xx.xx).

Is there any way to make the phone, either by MAC or IP network pfSense have an IP network of the Company?
It would be a firewall rule, a forwarder or something?

I try make a NAT 1:1 with Virtual IP and now I have a problem of one-way-audio.

Can be a problem with a Central or configuration of pfSense / Phone?

Any sugestion?

Thanx!
