Cant recommend not running a TOR exit node from home enough. When i was running mine for the ~6 months it was online, cox would shut my internet off for various reasons on a weekly basis.
Hosting a bridge from home is safe. They're not in the global relay list so nobody knows which IP to block. Middle relays should be safe to host from home but unfortunately some overzealous 3rd party lists of "evil IPs" include them.
I'm finding it difficult to understand what you're saying. You can already funnel all your traffic using a Tor SOCK proxy. So you don't need any changes to the TCP/IP stack to do what you seem to want. However, forwarding all your traffic increases the risk of fingerprinting, so you should give it careful consideration.
Let me clarify, because you are talking about something else. One of Tor's weaknesses is that you always need exit nodes, and running an exit node comes with certain risks. Now, what I'm saying is that if Tor was an integral part of the internet, then everybody would effectively be running exit nodes. The exit node and the destination node would be same thing. Government agencies wouldn't be able to take down exit nodes because that would mean they would have to take down the entire internet.
Not op, but it's my understanding that they can blacklist pretty much the same sites as for exit relays. So your email client may stop working, Also search sites, social media, etc.
Obviously, anyone can blacklist anyone for any reason on the Internet and relay nodes' IPs are public. But do they?
I run a relay node on my personal server and never had any issues. But 1) I rarely browse the Internet from that IP and 2) it's in OVH so if it were blacklisted, it could be because of that.
Also, depending on the country, you can be hold responsible if someone use your exit node to do something illegal.
As far as I remember, in France, you can get the same status as an ISP (don't remember the name though) to be able to run an exit node without being held responsible. But you will have to respect certain rules.
