Port Forward to clients

[AdrianoMormul]

Hello, thanks for the great work.
It solves a big problem which is port forwarding for client devices connected behind CGNAT.
Using the firewall feature, I was able to easily forward ports between 51820-51839 from the server to clients, for example. But I could only do this between the same ports, like 51820 to port 51820.
Is there a way to forward port 51822 to port 22 of one of the client devices for example?

Hello, I’m glad to hear that the port forwarding feature is helping you.

To enable more ports, you just need to edit your docker-compose.yml file and add extra ports.

There’s a comment there with the instructions.

Cheers!

Thanks. I had already done this, your documentation is very good.
But what I can't do is change the destination port (or the source port).
For example: I can forward port 55555 from the server to port 55555 on the client, but I would like to be able to forward it to another port, for example port 80. It would be a reverse nat from port 55555 on the server to port 80 on the client.
Searching on Google I saw that this is usually done with PREROUTING rules, but it can also be done with POSTROUTING + SNAT.
Is it possible?

Ooops! Looks like I’ve forgotten to add an option to change the destination port.

It should be supported.

I will add this feature on the next release.

cheers!

That will be great!
