<DIV><SPAN class=921570806-08112006><FONT face=Arial size=2>I have an internal
SIP server that handles registrations, and is used for incoming and outgoing
phone calls. It does not do any authentication. I'd like to set up SER in my
DMZ, and have it:</FONT></SPAN></DIV>

<DIV><SPAN class=921570806-08112006><FONT face=Arial size=2>1. authenticate all
requests. (this should be easy - I think I can handle it, although I would like
to get digest -> RADIUS auth against an Active directory

<DIV><SPAN class=921570806-08112006><FONT face=Arial size=2>2. forward REGISTER
requests to the internal SIP server, both for phones on the internal network and
for phones on the external network.</FONT></SPAN></DIV>

<DIV><SPAN class=921570806-08112006><FONT face=Arial size=2>3. forward INVITE
and ACK requests performing the correct handling of NAT, using RTP helper to
forward media when needed.</FONT></SPAN></DIV>

<DIV><SPAN class=921570806-08112006><FONT face=Arial size=2>Right now I'd love
to just get the REGISTER requests doing the right thing. Any help, or even
better sample config scripts would be much appreciated.</FONT></SPAN></DIV>
