‘based on the request’ is what’s actually causing the problem. Since the requests come through a proxy, every ‘remote_ip’ is always the local IP, so FS cannot make a determination based on that. I added a deny to the local IP which caused FS to offer the external IP and we can make that work if our customers turn on the NAT reflection. As a test, I modified switch_core_media.c:generate_m to throw in the local IP and that did fix our issue. I was hoping for a configuration option.

Actually no, what you do in this case is set the local-network-acl, it will then know which one to use based on the request.

This forces FS to always offer 'ext-rtp-ip'. Outside users work fine in that scenario. Internal users also work, as long as we turn on NAT reflection in our router. I'm looking for a way to not require that router change. If I can get FS to offer up both it's internal IP and 'ext-rtp-ip' as candidates in the initial INVITE, the browser could then use ICE to determine which IP address was correct. Is there a way to offer both and allow ICE on the client side to figure out which one to use?
