[j-nsp] ScreenOS and VoIP and NAT

Hi Ivan,

Have you read through the description for SIP with NAT, incoming calls covered on page 26?

http://www.juniper.net/techpubs/software/screenos/screenos6.1.0/ce_v6.pdf 

The examples from page 33 onwards do seem to describe your scenario, unless I am missing something obvious?

Regards,
Tony
