This is what you received from the far end? That looks horribly broken. Time to find out what device and what firewall.<div><br></div><div>-MC<br><br><div class="gmail_quote">On Wed, Aug 17, 2011 at 10:21 AM, Spencer Thomason <span dir="ltr"><<a href="mailto:spencer@5ninesolutions.com">spencer@5ninesolutions.com</a>></span> wrote:<br>

Our FS server is on a public IP on a dedicated server at one location and all clients are behind nat or vpn from other locations. We have a few "road warrior" clients when our employees travel. I'm seeing the following from one of the client devices. I'm not sure of any of the details of the router (or have anyway to control it) but for some reason the rport is sent with an invalid port number. Notice the 8 at the end of the port number is duplicated. I'm seeing the same behavior from both a Bria client and Zoiper. Is there any way to work around this?<br>
