I thought it was `18332`.

Sorry for the late response. Using port 18333 has no effect unfortunately and I still get "178.128.162.252:18333 is unreachable."

<p>Testnet is a distinct although largely similar protocol.  Bitnodes would need to specifically support it for it to work with it.  I can't find any evidence that bitnodes has any testnet support or a testnet edition.</p>

This would explain the situation, thank you. Do you have reference on where the two protocols diverge?

There are many small differences, mostly configured via settings in https://github.com/bitcoin/bitcoin/blob/master/src/chainparams.cpp#L182

<p>I have used the bitnode's own script to install a full node on an Ubuntu 16.04 Digitalocean droplet. I can verify that my node is up and running by checking the IP with port 8333 on Bitnode's <a href="https://bitnodes.earn.com/" rel="nofollow noreferrer">check node</a>. However I need a testnet node so I next added the following line to the config file:</p>

<pre><code>testnet=1
</code></pre>

<p>It seems the above line produces the desired effect of turning the node into a testnet node and this can be verified through bitcoin-cli commands. But the node will no longer be accessible from Bitnode. Is Bitnode designed to only work with nodes on the main blockchain or am I missing a necessary step?</p>

Testnet is a distinct although largely similar protocol. Bitnodes would need to specifically support it for it to work with it. I can't find any evidence that bitnodes has any testnet support or a testnet edition.
