Stupid Mac Ethernet question

I work for a medical software company. The software we sell and support replaces the TCP/IP transport layer with a proprietary layer that uses a random, non-standard length, encrypted UDP packet. It's non-routable but works fine in a local environment. Bad software design I know, but I didn't write it, I just have to support it. It works really good except when a Linksys switch or router is involved. Ninety percent of my customer's network performance problems go away when I pull the Linksys gear and replace it with Netgear, D-Link, 3Com, AOpen or generic no-name crap. No problems with any other brand, just Linksys. I think the Linksys chipset or firmware is so rigidly designed that anything out of the M$ ordinary world causes it to barf and lockup. -- www.blackcube.org The Texas State Home for Wayward and Orphaned Computers
