I have an apple tv 4k. I'd like it to use a proxy. But there's no way to add a proxy for an apple tv 4k in an apple tv 4k.
I also have a Linux NAS that has two Ethernet ports.
And a Linux server outside my country that runs nothing but sshd.
I don't want to config anything on my router or using apple's Configurator.
I want to connect the apple tv 4k to the second Ethernet port on the NAS. Then create a docker in my NAS that runs sshuttle. So there's no TCP-over-TCP issue. Then let apple tv 4k connect to the internet of the docker that runs sshuttle in the NAS while still have access to the NFS service of the NAS.
I've tried to use the following command, but it didn't work.
sudo iptables -t nat -I POSTROUTING -s 169.254.10.10 -j SNAT --to-source 172.18.0.2This does give apple tv 4k internet access, but it's the internet of the NAS rather than of the remote Linux server.
sudo iptables -t nat -D POSTROUTING 1
sudo iptables -t nat -I POSTROUTING -s 169.254.10.10 -j SNAT --to-source 192.168.123.123How should I configure the iptables? What should I do?

After further learning on the internet, I realized that this is not something that iptables can do alone. It seems that I should configure the route rule on my Linux NAS. But this is still too hard for me to understand. I put the network information below. Please help me with How To Configure Route Rule to Let Apple TV 4k Use The Internet of The Container. Thanks!!
