Podman Quadlets Arr-Stack Setup And Networking

I need some help if anyone could take the time and has the knowledge:
I'm basically new to podman and namespaces, relatively new to linux and a noob at networking. So figuring this out and getting it to work took many more hours than I would like to admit, but I still have a few problems. I have all my current Quadlets below in the spoiler (seperated by "---", assume user123 = UID 1000). I am on Bazzite, rootless Podman, which probably makes this even harder.

Questions:
-
- If I use "podman exec ip route" (on e.g. qbittorrent) the default route goes through my actual network interface (actual ip adress) which I very much do not want (or through my killswitch dummy network from my VPN if on, which is better but still not ideal). Is there a way to completely remove my actual network from a container's eyes? "podman exec ip addr" shows 1 lo (local), 2 my actual network, 4 tun0 from gluetun. The traffic does go through gluetun correctly, but I don't trust it 100%. Having the containers separated and NOT inside a pod gives the same result, since the containers share the network namespaces from the gluetun container when I do "Network=container:gluetun" (same as just having them in a pod as far as I understand). I tried to also create a podman network without a default gateway, but then gluetun cannot connect to the VPN in the first place.
EDIT: A few notes: I thought gluetun was supposed to set the default route (but it seems it either doesn’t or can’t). My goal was to only have gluetun see my computer’s network and have the containers only see local network and gluetun’s tun0 network (with default routing through tun0). AFAIK pods share network namespaces, though, so that might not be possible? (even without pods?)
-
- My setup works but is quite convoluted and probably has many unnecessary lines, so please give me any improvements you see
-
- Is User=1000, Group=1000, even sensible? For example in the homepage container those lines result in the container showing User "1000:1000" (from podman inspect). Would User=0, Group=0 (or no lines since I use UserNS=keep-id in the pod?), which shows as User=root (podman inspect) mean that it has actual root access or just that it is root INSIDE the container?
Thank you in advance for the answers, in case I don't reply to your comment specifically.
