[Ltsp-discuss] Trouble running LTSP over multiple network segments

2003-11-17 Thread Jeff Self
I've successfully got LTSP working on one of my servers. I can connect a PC to the same switch and boot up with either a boot disk or using PXE. But I am unable to get a thin client to work that is sitting on another network segment. I've put a dhrelay on a PC on the other network segment. When I
