SharePoint 2013 publishing through a single NIC TMG 2010 solution.

Please can someone advise if it is supported by Microsoft to publish SharePoint 2013 through a single NIC TMG 2010 server.

To be clear the TMG 2010 server only has one Network Card and is currentkly used to reverse proxy Outlook Web Access but there is now a requirement to publish HsarePoint 2013 through it.

Thanks in advance.
