DNAT with iptables over wireguard hosted on a VPS to host services behind a firewall/GNAT.

This is a short description of how to host services, using STORJ node as an example, on a host behind GNAT, or otherwise restrictive firewall, by forwarding packets through WireGuard endpoint on a relatively fast nearby VPS. This is not specific to Storj, and can be adopted to hosting other services.

As an example we will use an Oracle Cloud instance. Free tier still provides 10TB of monthly traffic that is sufficient for most node operators. Just make sure to create an account in a closest datacenter to minimize extra latency.

Notes on configuring the cloud instance

1. Create the oracle compute instance (ideally, Ampere, because they are awesome, but if that is not availabe, any other will do too).
2. Pick any OS you prefer, here we'll describe Ubuntu, as a most popular one.

Disk Speed Test (Read/Write): HDD, SSD Performance in Linux

From this article you’ll learn how to measure an input/output performance of a file system on such devices as HDD, SSD, USB Flash Drive etc.

I’ll show how to test the read/write speed of a disk from the Linux command line using dd command.

I’ll also show how to install and use hdparm utility for measuring read speed of a disk on Linux Mint, Ubuntu, Debian, CentOS, RHEL.

Take the average result: To get the accurate read/write speed, you should repeat the below tests several times (usually 3-5) and take the average result.
