I thought Vintela was not available locally (US), only in Europe. Ok, will look. If you have a NAT tunnel from compute nodes to rest of the WAN you might not need a proxy, though the performance hit could be severe for rapidly executing systems, or those that check permissions. Better to have a local proxy for this if possible. -- Joseph Landman, Ph.D Founder and CEO Scalable Informatics LLC, email: landman at scalableinformatics.com web : http://www.scalableinformatics.com phone: +1 734 786 8423 fax : +1 734 786 8452 or +1 866 888 3112 cell : +1 734 612 4615
