Host Networking

Set Up Switch - HyperV Networking

This section details how to set up a NAT network and VM Switch on a HyperV server.

Note that the examples below are using the 192.168.255.0/24 address space. Use of address ranges that do not conflict with locally available addresses is probably a good idea.

The below commands will:

Create a new VM Switch
Update associated vNIC on host
Create a new NAT network and configure the IP range of that network
Add a firewall rule to allow traffic from the VM to get to Packer on the host

New-VMSwitch -SwitchName "NATSwitch" -SwitchType Internal
New-NetIPAddress -IPAddress 192.168.255.1 -PrefixLength 24 -InterfaceAlias "vEthernet (NATSwitch)"
New-NetNAT -Name "NATNetwork" -InternalIPInterfaceAddressPrefix 192.168.255.0/24
New-NetFirewallRule -DisplayName "Packer_http_server" -Direction Inbound -Action Allow -Protocol TCP -LocalPort 8000-9000

Port forwarding rule.

netsh interface portproxy add v4tov4 listenport=8080 connectaddress=192.168.255.100 connectport=8999 protocol=tcp

Run

This command

packer build -force -on-error=abort -var-file="data\centos8.json" .\centos-hyperv.json
