Thanks for this, I really appreciate it!
So I’m working through the instructions you’ve listed and I’m trying to determine how to apply them. I’ve essentially reset everything as best as I’m able to ensure I’m not being tripped up by old mistakes. I’m trying to add the routing to the table in the network settings, but it doesn’t seem to apply properly?
I’ve tried applying it via the terminal and whilst I can get it to show up, it disappeared after a reboot?
I wondered if it was related to the preserve user defined networks option in the docker configuration? I tried forcing the DNS with the add additional parameters in the config of my firefox container, but it didn’t seem to work. Am I going to have to set some of this stuff up in a script which runs at boot or something to apply these configurations properly? I don’t feel confident that I know what I’m doing well enough to mess with IP tables at this point.
