Using Helia to Publish Contents via Reverse SSH Tunneling

[a4smanjorg5]

How to publish contents via ssh -R0:127.0.0.1:4001 serveo.net ?
I tried using this configuration but it still doesn't work:

...
addresses: {
    announce: ['/dns4/serveo.net/tcp/45400'],
    listen: ['/ip4/127.0.0.1/tcp/4001'],
},
...

My connection is also using NAT, no UPnP, and can only forward it using reverse ssh tunneling.
