When using the NAT mode, being the network prefix 10.0.2.0/24, I see the following:
- 10.0.2.1 is not assigned (no ping response)
- 10.0.2.2 is assigned to the internal interface of the NAT router (from the routing table; ping ok); the corresponding MAC address is 52:54:00:12:35:02 (from the ARP table or from the capture of ping packets)
- 10.0.2.3 is assigned (ping ok); the corresponding MAC address is 52:54:00:12:35:03, different than internal router interface’s MAC address (from the ARP table or from the capture of ping packets).
- 10.0.2.4 is assigned (ping ok); the corresponding MAC address 52:54:00:12:35:04, different than the two previous MAC addresses (from the ARP table or from the capture of ping packets).
- 10.0.2.5 is not assigned, etc.
- 10.0.2.15 is assigned to the VM interface.
- DHCP server is bound to 10.0.2.2, the internal router interface (from the capture of DHCP packets or other)
When using the NAT Network mode, being the network prefix 10.0.2.0/24 and the DHCP service enabled, I see the following:
- 10.0.2.1 is assigned to the internal interface of the NAT router (from the routing table; ping ok); the corresponding MAC address is 52:54:00:12:35:00 (from the ARP table or from the capture of ping packets)
- 10.0.2.2 is assigned (ping ok); the corresponding MAC address is 52:54:00:12:35:00, that is, the same as the internal router interface (from the ARP table or from the capture of ping packets); therefore 10.0.2.1 and 10.0.2.2 are both assigned to the internal router interface.
- 10.0.2.3 is assigned (ping ok); the corresponding MAC address is 08:00:27:5f:59:1f, different than internal router interface’s MAC address (from the ARP table or from the capture of ping packets).
- 10.0.2.4 is not assigned, etc.
- 10.0.2.15 is assigned to the VM interface.
- DHCP server is bound to 10.0.2.3, which is not the internal router interface (from the capture of DHCP packets or other)
Thanks
