Why do I see two "networks" under "System Preferences>Network>Network Port Configurations"? One is labelled "Parallels NAT" and the other is "Parallels Host-Guest". Thanks// Chris Freeborn
Their names stand for themselves - they are to support Shared Networking and Host-Only modes of Parallels Desktop networking. It is not recommended to alter them unless you're absolutely positive you don't need both of these modes.
