How to make a connection between two guest VMs?

[Changhee Oh]

I have create two guest VMs(w1, w2)and can ssh into both of them from the host Mac.
But I can't ping or anything from w1 to w2 or from w2 to w1.
Please someone help me to resolve this issue.

• Host Mac: 192.168.64.1
• w1: 192.168.64.8
• w2: 192.168.64.9

Ping test result

• Success: host Mac -> w1, w2
• Success: w1, w2 -> host Mac
• Fail: w1 -> w2 (Destination Host Unreachable)
• Fail: w2 -> w1 (Destination Host Unreachable)

HTTP test result (via curl)

• Success: host Mac -> w1, w2
• Success: w1, w2 -> host Mac
• Fail: w1 -> w2, w2 -> w1
• Success: w1 -> w1, w2 -> w2

This is currently a limitation of Apple. You can workaround it by setting up a VPN server on your Mac, and connect your VMs to the VPN. (I recommend Wireguard for this)
