can guest talk to each other in NAT?

[kasicass]

I'm running two guest in my VirtualBox.
host, 192.168.0.76
debian, 10.0.2.15
openbsd, 10.0.2.16

in debian,
$ ping 192.168.0.76
PING 192.168.0.76 (192.168.0.76) 56(84) bytes of data.
64 bytes from 192.168.0.76: icmp_seq=1 ttl=64 time=0.852 ms

$ ping 10.0.2.16
PING 10.0.2.16 (10.0.2.16) 56(84) bytes of data.
From 10.0.2.15 icmp_seq=1 Destination Host Unreachable

Thx a lot for help.

This isn't like VMWare. VMs using NAT are completely separated. If you take a closer look at the IP address they get, it's all the same (10.0.2.15).
