Q.
Dear Ab-end: I have Novell's BorderManager. I also have a customer who would like to exchange information across a Virtual Private Network (VPN) with his partners and costumers that already have other VPN products. Can the VPN function of BorderManger be used with other products on the Internet market, such as Unix firewalls? Also, do you know of any return- on-investment studies on how much Internet traffic bandwidth you can eliminate across WAN links with the use of BorderManger?

Dear Anxious: There is still no defined standard for VPN. In the current release, BorderManager's VPN feature release uses a proprietary encryption scheme and can only work with VPN servers within one NDS tree. The next release will support the standard SKIP and IPSE (AH and ESP) protocols, but still requires there to be two (or more) BorderManager servers within the same NDS tree. I am not aware of any R.I. studies, but customer feedback as well as our experience shows proxy hit rates of approximately 40 to 70 percent.
