Thanks for the correct answer to my earlier problem! Now I've got my ONTAP 8.1 7-mode sim working nicely in VMware Fusion on Mac OS X 10.7.5.
In Mac OS, I can see a private virtual network on Link#8 with addresses in the 192.168.199/24 range. I assigned the sim's e0a to 192.168.199.99, with no conflicts. None of the 3 other vNICs have an IP address. All the sim's vNICs are configured private to host. I also have a Win7 VM running on the same VLAN, but with NAT.
The default gateway on the Win7 VM appears to be 192.168.199.2. I assigned that to the ONTAP sim also, but I can't ping the gateway, or the Mac host, or the Win7 VM from the sim. What must I do to establish connectivity?
