VPN's and fragmentation
Well I would imagine most of you have Virtual Private Network’s (VPN) on your corporate network. That plus the use of an IDS can potentially give you problems, as often the use of VPN’s will result in fragmented traffic. Had that very problem occur to me a couple of years ago, and the end result was some really bizarre fragmented traffic. It took a while to figure out what the problem was but eventually we were able to trace it back to the VPN. Any of you guys ever experience the same scenario?
