VMware Fusion hosts my test beds for PowerNSX. This runs on my work laptop which is a 2015 MacBook Pro that has an i7, 16GB, and a 1TB SSD. I access the environment via SSH from my desktop iMac. These workloads run on my laptop so when I travel my test beds are not dependent on home infrastructure.
I run the following workloads on the MacBook Pro:
– vCenter Server Appliance
– NSX Manager
– Log Insight
These VMs are connected to Custom Networks. The network in question is
192.168.103.0/24 and the checkbox
Allow virtual machines on this network to connect to external networks (using NAT) is ticked. This results in the workloads being on a local network
I wanted to be able to access the Log Insight interface hosted on my laptop and as such I needed to port-forward to the Log Insight virtual machine. This requires editing on the Fusion network scope the workloads are attached to.
The network configuration files are stored their respective folders within the VMware Fusion preferences folder.

The network of interest in this case is

nat.conf file. It includes which IP address will be used as the source IP for NAT, what inbound TCP connections can be made, and much more. The
[incomingtcp] field is what is of interest.

192.168.104.131:443 which is the Log Insight instance. With this configured one must restart network services.

VMware Fusion is a handy tool for home lab environments and especially environments on the run. Being a VMware employee I am privy to what is coming and I pretty much love this tool more and more with each release.
Wondering how I run VM’s with more memory than my actual device has? Check out these other Fusion blogs below!
