Trouble in IPSec VPN land
Trouble in VPN land
Meanwhile, the Big Three are becoming frustrated over
interoperability problems with the multivendor VPN gear used on the ANX,
a huge privately run e-commerce network that is mainly for the automotive
industry. As has been the case since the ANX was founded two years ago,
the service is only provided by ISPs that have met strict quality
controls approved by technical staff of ANXeBusiness, a division of SAIC
that bought the ANX from the AIAG a few years ago. Trading partners that
want to use ANX, including those outside the auto industry such as
Boeing, must use IP Security (IPSec)-based VPNs to encrypt data with
other ANX trading partners.
However, VPNs have been the sore spot for ANX because it has proven
impossible to get different vendors' VPN gear to work together despite
extensive IPSec equipment testing. Erik Naugle, CTO at ANXeBusiness,
explains: "The standard has enough loopholes [that] you can be
compliant with the specification but not be
interoperable."
