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 check node. However I need a testnet node so I next added the following line to the config file:
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?
