Your help is greatly appreciated. I apologize for the length > of this email. Routing, son, routing. Look carefully at the subnet mask of eth1: eth1 Link encap:Ethernet HWaddr 00:00:00:00:00:00 inet addr:147.185.179.65 Mask:255.255.0.0 All of your real network LAN traffic that was previously being bounced back through the CTC connection is now flowing into the virtual bit bucket. Fix up the subnet mask (255.255.255.128?) and all will be well (he said hopefully). Alan Altmark Sr. Software Engineer IBM z/VM Development

That range includes your CTC address, which probably stops it working. Choosing a different address for eth1 would probably be the simplest solution. Richard

In a couple of cases I had to use: qeth-1,0x To have the driver pick the device automatically.
