If FreeSWITCH is configured in bypass-media mode, and the endpoint behing NAT cannot use any of the NAT avoiding techiques to send public IP in the SDP (STUN etc.) then you'll have issues.<br><br>You can do what do I do, which is to make different sofia profiles for NATed and non-NATED endpoints (FS has many server-side nat traversal mechanisms).<br>

</div>Thanks but the context I was refering to is...<br>
1. Freeswitch is configured in BypassMedia mode<br>
2. The firewall and the local end-points are configured so that a<br>
series of UDP ranges are mapped to their respective end-point (eg.<br>
UDP100-1003 for extension #1, 1004-1007 for #2, etc.)<br>
... so that RTP packets flow directly between the two end-points<br>
<br>
Brian says above that there might be cases where NAT could be a<br>
problem. When could this happen?<br>
<br>
I'd like to get to the bottom of this so that in case a server is a<br>
bit short on CPU/network power, I know that there's the alternative of<br>
RTP packets by-passing the server... but I also need to know what<br>
issues this setup can cause.<br>
<br>
Thank you.<br>
