fwdctl

fwdctl is a simple and intuitive CLI to manage forwards in your Linux server.

How it works

It essentially provides commands to manage forwards, using iptables under the hood.

Let's do an example:

Suppose you have an hypervisor server that hosts some virtual machines inside itself. If you need to expose an internal service, managed by one of these VMs, you can use fwdctl from the hypervisor to add the forward to expose this service.

To do so, you have to type this easy command:

sudo fwdctl create --destination-port 3000 --source-address 192.168.199.105 --source-port 80

That's it.

Installation

Linux x86_64

curl -s https://raw.githubusercontent.com/alegrey91/fwdctl/main/install | sudo sh

Seccomp (experimental)

I've recently added a new functionality to trace the system calls used by fwdctl during the test pipeline.

This is done by using another project of mine: harpoon.

Thanks to this, at the end of the pipeline, we have a seccomp profile as artifact. You can use this to run fwdctl in a more secure way.

Find the seccomp profile here: fwdctl-seccomp.json.
