robert,
with limited info below, are you port forwarding on the router with the public IP, ports 10,000-20,000, 5004, along with 5060?  and the other router (internal, I assume)???

how do you have two firewalls configured with one * box?
do you have captures on both sides of the internal (I assume) router?... 
if you want to call me, just send me an email... will be available till 11p EST.

I have a server behind a firewall.  It is publicly addressed.  Should 
NOT be trying to NAT (how would I know).

The connection is a SIP trunk to Broadvoice.  I am calling the 
Broadvoice # from my cell and the call is being routed to my server.

With one firewall the INVITE contains information for the RTP session to 
be with broadvoice servers with different addresses.  It works.

With the other firewall the INVITE does NOT contain any other IP 
addresses, and the call goes through but no voice (duh).

I have captures of both.  I would include them in this message, but I am 
a little concerned that if some of you get the Registration, you will 
crack my secret...

PLEASE help me out on this.  I am absolutely pulling out my hair on it 
(and I don't have much).  I have stared at the Wireshark displays and 
just don't see it.  I have turned on logging on the failing firewall, 
and am not seeing any messages being dropped or rejected.
