VirtualBox network modes

3rd November 2020

As covered in the VirtualBox networking docs, the quickest overview into different networking modes is the following table:

	VM ↔ VM	VM → Host	Host → VM	VM → Net/LAN	Net/LAN → VM
Not attached	-	-	-	-	-
Internal Network	+	-	-	-	-
Host-only	+	+	+	-	-
NAT	-	+	forwarded ports	+	forwarded ports
NAT Network	+	+	forwarded ports	+	forwarded ports
Bridged	+	+	+	+	+

In short, bridged networking happily allows everything, while other less permissive modes give you granular control over your network security.
