FWIW, we had problems with a MacOS Web Server (Web*, MacOS 8.6) and a 1600 Series Cisco router whereby the Mac crashed every time an external request came through the router. Installing the latest (MacOS 9) version of Open Transport fixed the problem. I mention this as you could try just installing the latest version of OT (swapping in 2 files did it for us) and you may fix the problem. A simple trick to try.
