You can't put "HOST" in the HOME statement. Just subnet masks. If you get errors in your PROFILE, it's hard to tell what worked and what didn't. You gotta have a clean startup. > 192.168.099.227 255.255.255.000 LLINUX27 As I said previously, you put only VM IP addresses in the HOME list, not other hosts' IP addresses. What is VM's IP address w.r.t. LLINUX27? You MUST choose a unique IP address for the VM TCP/IP end of EVERY p2p connection, whether it's CTC or IUCV. You need to define a subnet that contains both VM and LLINUX27. This is why the choice of subnet mask 255.255.255.252 -- it defines a subnet with exactly two (and only two) hosts in it. Unfortunately, a /30 subnet can't have .227 as a host address because it's the broadcast address for the the .224/30 subnet (only .225 and .226 can be assigned). Now, if you broaden the mask to /29 (255.255.255.248), then you can have them both in the same subnet. > GATEWAY > ; Network Subnet First Link MTU > ; Address Mask Hop Name Size > ; ------------- --------------- --------------- ---------------- ----- > > 192.168.099.227 HOST = LLINUX27 9216 That entry looks good, AFTER you create a subnet mask that allows it and the matching HOME IP address to coexist in the same subnet. The presence of the HOST route will enable you to use that /29 to cover multiple p2p pairs. The .224 network will be located "behind VM TCP/IP" in all cases, but the host routes will tell the stack which interface to use. Alan Altmark z/VM Development IBM Endicott
