Get list of forwarded ports

Question

My system has several port forwarding settings active. Among others, I have some Vagrant machines with port-forwarding configured:

  Vagrant.configure("2") do |config|
    config.vm.network "forwarded_port", guest: 22, host: 33022
    config.vm.network "forwarded_port", guest: 80, host: 33080
    config.vm.network "forwarded_port", guest: 443, host: 33443
  end

I have several machines with port forwarding configured, and other tools doing port forwarding (ssh ...). I would like to verify that the system config is as expected.

Is there some way to list all these port forwarding rules?

How about `iptables -t nat -L PREROUTING -n -v` (will require privilege)? — MadHatter, Mar 05 '18 at 06:58

Haven't worked much with vagrant before, but you could use

netstat -tulpen

to list all port bindings and their associated process.

port forwarding in iptables does not have listening ports. – Gerald Schneider Mar 05 '18 at 09:49
Damn, you're right. I shouldn't answer here while still half asleep :/ – M1k3y Mar 05 '18 at 09:51
