Unable to connect two virtual machines

[keiou]

According to the manual in Chapter 6.6, using internal network configuration will allow two or more virtual machines to connect to each other. And the Virtualbox support driver will act as a network switch.

I have created two VM's, used the internal network configuration and left the default name as it is. But both VM's still cannot see each other.
I have also tried to set the IP address to DHCP first then to static but no success.

Does anybody know if I may have missed something?

Thanks.

I was finally able to make it work. I just disabled the firewall for the domain.
