Matt, Thanks for getting to this one before I could... :) Everyone else, The best explanation that I have is that they want to authenticate exactly where you're coming from to prevent fraud. A lot of the various on-line shopping sites, etc. will not allow a connection that they can't authenticate. Being able to authenticate where a sale comes from allows them to track it back, etc. If your ISP doesn't have this set up properly, it's not going to work for you. When I worked at BlitzNet, we had customer support calls that I had to handle about this. People taking their business elsewhere because the entire staff that I replaced didn't have a coherent strategy to make things work properly. That's not a good sign. Maybe it's not a requirement of 128 bit encryption, per se, but the applications thereof on websites. --- Andy > -----Original Message----- > From: owner-freebsd-questions@FreeBSD.ORG > [mailto:owner-freebsd-questions@FreeBSD.ORG]On Behalf Of Matthew > Emmerton > Sent: Sunday, April 01, 2001 10:27 PM > To: Randall Hopper; Andrew C.
