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

You can list the nat rules by the following command:

VBoxManage showvminfo #{vmid}

You then get a lot of information about your VM including the forwarding rules, for example:

NIC 1 Rule(1):   name = ssh, protocol = tcp, host ip = 127.0.0.1, host port = 2022, guest ip = , guest port = 22
