Two different systems... LPAR1 is /22. The netmask which I didn't show is: 000.000.003.0 The netmask I did show, which is /24, is for the second level system on LPAR0.
I took down LPAR1 last night, and brought up the second level system, now first level. Just to see if the supernet was getting involved and preventing me doing what I wanted. But I had the same problems. Tom Duerbusch THD Consulting >>> [EMAIL PROTECTED] 12/5/2006 10:53 AM >>> You say /22, but your netmask is set for /24.
