Not a major problem, but, using System Configuration from the Control Panel to change IP and gateway, I would get SIOCADDRT invalid argument and network unreachable errors if setting the subnet to 255.255.255.248 (which is the correct subnet). Setting the subnet to 255.255.255.0 seems to work ok. Using Network Configuration from the Control Panel seems to work ok with the 248 subnet. I was able to duplicate this on several machines.
Michael: This was a linuxconf issue, right? Is it it fixed?
I don't think that this bug exists in 5.2. I have used a .248 successfully at home.
