On my lan, i am using tcpip for net access and ipx/spx for my filesharing (since my cablemodem doesnt pass ipx). My speeds when transfering files between computers is slow (700KB/s) for the 100mbit connection. I cant use tcpip for filesharing because the dynamic IPs of each machine are on different class C's (that means they cant talk to each other directly, they need a gateway, which would bottleneck the speed of my lan to the speed of my cablemodem). Any ideas on how to speed things up?
