A Short Introduction to Troubleshooting Docker Networks

I recently just built an unRAID rig which has now been deployed to my DMZ. It’s great, but something I have been struggling with is that periodically my FileZilla docker container will be unable to connect to my FTP server, erroring out with “ENETUNREACH – Network unreachable”. It seems to be exacerbated by large file moves (like when I’m moving whole directories).

This is a companion discussion topic for the original entry at https://engineerworkshop.com/blog/a-short-introduction-to-troubleshooting-docker-networks-how-to-fix-enetunreach-network-unreachable-in-filezilla/
