No ARP responses on a NAT Network

Reported by: lf Owned by:
Component: network/NAT Version: VirtualBox 5.0.10
Keywords: natnetwork Cc:
Guest type: Windows Host type: Linux

Description

I have two Windows guests on a NAT network who refuse to communicate with each other. I debugged the issue with arp -a -v and found that they weren't finding each other with ARP. A packet capture and analysis with Wireshark confirmed this.

Logs, outputs of ipconfig /all and a pcap are attached.

Do you have a simultaneous packet capture from the other VM?

Actually, your VMs are on different networks, so no wonder they don't see each other. The first one is on "internal", the second on "int".
