Is your feature request related to a problem? Please describe.
The "Exit Node" may route to destinations not desired, e.g. RFC1918 address space. It would be useful for those who know about such things, to include a tick-box saying "exclude Bogons". A bogon is an IP address range which has not been allocated by IANA or one of their delegates.

Describe the solution you'd like
Ticking this box would change the route from 0.0.0.0/0 to a collection of routes, as listed here: https://www.cidr-report.org/bogons/allocspace-prefix.txt

Describe alternatives you've considered
You could exclude RFC1918 addresses (10/8, 172.16/12. 192.168/16), plus the RFC5737 addresses (192.0.2/24, 198.51.100/24 and 203.0.113/24) and RFC2544 (198.18/15), and the other "special" subnets (0/8, 100.64/10, 169.254/16, 192/24, 192.88.99/24, 224/4, 240/4).

Is there any Progress on this? I think quite a lot of people wanna route their roadwarriors internet traffic through the tunnel but not expose the full lan / dmz to vpn?

this really would be helpful, especially with always on vpn. my phone cant cast to anything because the mdns addresses route though the exit node. right now i toggle off the exit node. this would solve the issue.
