LIST natpf rules in Virtualbox/Vagrant

Question

I often get errors like this when running Vagrant:

VBoxManage: error: A NAT rule of this name already exists
VBoxManage: error: Details: code NS_ERROR_INVALID_AR         


        

Answer 1

This got the job done for me:

VBoxManage showvminfo $VM_NAME --machinereadable | awk -F '[",]' '/^Forwarding/ { printf ("Rule %s host port %d forwards to guest port %d\n", $2, $5, $7); }'
