Hi

I am trying to establish network connectivity between two Oracle Linux Server 6.5 guests with different subnet for the public interface (eth1).

1st guest:
eth0 - NAT - DHCP (for internet)
eth1 - Host Only adapter- 192.168.46.112 ( public interface for Oracle RAC 11g)
eth2- internal network - 192.168.2.112 (private interface for Oracle RAC 11g)

2nd guest:
eth0- NAT - DHCP (for internet)
eth1- Host only adapter - 192.168.36.112 (PUBLIC interface for Oracle RAC 12c)
eth2 - internal network - 192.168.3.112 (private interface for Oracle RAC 12c)

When both VMs are powered on, they cannot ping each other, even though I turned off the firewall. What can I do to allow the two VMs to be able to ping (and communicate) with each other, even though they are in different subnets?

Networking 101. Unless you are using something to do routing, machines on different subnets will not see or talk to each other.

Hi

Thanks for your response.

is there anything that can be easily used in virtual box to providing routing between two VMs with different subnets?

Not in VirtualBox but I like pFsence. Linux based, but easy to setup and has a small footprint.
