<br>
We&#39;ve just upgraded (switched back to building from svn in case this<br>
was a git migration issue) and all our phones behind various networks<br>
on NAT won&#39;t registered anymore, whereas on version dated 2010-02-22<br>
20:06 (don&#39;t have the revision) all these phones were fine and handled<br>
the the FS NAT features. No NDLB features on enabled or rport. They<br>
weren&#39;t on the 2010-02-22 20:06 version either.<br>
