Chuck,

Always  difficulty with pfSense and SIP. The following I copied from the
pfSense [
http://www.pfsense.org/index.php?option=com_content&task=view&id=40&Itemid=43]
website.

"SIP Limitation - By default, all TCP and UDP traffic other than SIP and
IPsec gets the source port rewritten. More information on this can be found
in the static port documentation<http://doc.pfsense.org/index.php/Static_Port>.
Because this source port rewriting is how pf tracks which internal IP made
the connection to the given external server, and most all SIP traffic uses
the same source port, only one SIP device can connect simultaneously
to a*single server on the Internet
*. Unless your SIP devices can operate with source port rewriting (most
can't), you cannot use multiple phones with a single outside server without
using a dedicated public IP per device"


--

If my Asterisk server on the internet (Hosted outside the network). Then my
phones on the local network one phone only able to connect at a time to the
Asterisk.
