You may have to put a static route in the PBX to route back out through
that firewall to go to the ITSP's IP addresses.

Subject: [sipx-users] Separate IP for connection to ITSP

Hi all,
        I have purchased a dedicated circuit from my telephony vendor
that  
will be used exclusively for SIP trunking.  It will have a different  
IP address than my normal site internet connection.

My question is, will this cause me problems with sipx?  In particular,  
when users outside my local network need to connect to the sipx server  
(for web interface or to register roaming SIP phones) they will  
connect through the normal WAN IP address of my site firewall (which  
is also the address referenced in my (split) public DNS records.

However when sipxBridge talks to my ITSP, they will connect through a  
different public IP address (that of my dedicated bandwidth).

WIll this cause problems getting synced up with my ITSP?  Is there any  
config in sipx I need to do to facilitate this?

Thanks,

Jeff Gilmore
