Oh, something else to try: I checked through my notes and discovered that I had gotten UDP to work in a similar configuration before. What I did was bind the IP address to fxp0 instead of em0. By doing this, the kernel seems to send the data at a pace suitable for the slow interface. -Jon On

I'm having some problems with NFS serving on a FreeBSD 5.4-RELEASE machine. The FreeBSD machine is the NFS/NIS server for a group of four Linux clusters. The network archictecture looks like this: 234/24 234/24 Cluster 1 ---|
