Good evening,
Supplied virtual machine uses network type of NAT. Another allowed network
type is "bridged ..." . This second method is useful, because You can
communicate with another running virtual machines on Your host . For example
if another virtual machine is Solaris10 , You can enter this command on
Solaris :

svcadm enable telnet

and You can telnet from Coherent to Solaris.
One condition must be fullfilled on Coherent side. arp table must contain
IP address of the Solaris. Run command

arp ipro100

and check this. If not wait few seconds or minute, run arp again and it should appear in a shown list. If not You can add this entry manually

arp ipro100 add 4 192.168.1.x 12:3d:32:1e:10:d2

where third argument is the location in the table, fourth argument is the IP
address of Solaris and fifth argument is example of Ethernet address. Third argument must be equal or greater than 4 and must be different for each address
You add to the arp table.
