I have two questions and would really appreciate any help on resolving this:
We have a Cisco Pix 525 with IOS 8.04. I am trying to NAT a range of ports via ASDM to support a Mitel 5312 remote handset and Passive FTP.
I couldn't find solution to NAT a range of ports to a private IP address, so I assigned a public IP address to the Phone system and NAT all ports to the private IP address of the phone system via Pix.
I have got to a point where, when I dial on the handset it rings another extension but no voice. I have some experience with Cisco routers, but new to Pix and Mitel.
