I feel like I'm losing my mind. A few days ago, all of my containers running on Docker Desktop on my Windows Server host were working nicely. I had NFS volumes set up on a few of them to reach my synology NAS on my local network, and things were working fine. I've done so much digging and tweaking over the last few days, so I can't be certain where all I've broken this connection further, but I woke up one morning and the containers that all had connections to my NAS via NFS volumes were no longer working. I hadn't restarted my host, I don't know what changed. Containers like NPM that I had set up for my internal DNS would no longer redirect to any IP that wasn't within my docker network (for example, I run Plex NOT in a container on my host PC). I had all of my containers on the default bridge network, and now nothing on this docker network can connect to anything on my local network.

I've tried setting static routes in my router, changed a lot of configurations, dug through tutorials, guides, and posts all weekend, but I couldn't make any progress in figuring things out. I'd really appreciate some help on this one, and can provide more details, logs, compose files, when needed. Just don't want to dump everything at once

Edit: For anybody looking for a solution, I bit the bullet and installed proxmox. Running my docker containers on an Ubuntu VM now. Linux Docker seems to be working much better now. I suppose the answer is just "run Docker on a Linux OS," since Docker on Windows seems to be limited. Plus, it gives me something new to play around with.
