Port forward socket timeout

[alex_potemkin]

Hello,

I've setup opnsense in front of minio server and started getting the following error on a big files upload:

> Socket timed out without establishing a connection HTTP Code: TimeoutError

The error appears after ~30 minutes of upload.

OPNsense was doing nothing more than just a port forwarding (port nat).

Is there any settings I can adjust to make sure it won't shut down the active socket?
