Port Forwarding To a VirtualBox VM

Posting this little tidbit for myself. Turns out VirtualBox has a lot of
interesting NAT options:

Nat Forwarding – VirtualBox

To forward a port from a host machine to a VM, all you need to do is
find VBoxManager (.exe at the end for windows) and type:

VBoxManage modifyvm "VM name" --natpf1 "guestssh,tcp,,2222,,22

And now you have forwarded port 2222 of your host machine to 22 of your
VM.

Would love to know how to delete these rules though.

EDIT: just found it, awesome: VBoxManage Command Reference

--natpf<1-N> delete <name>
