[sslh] Better --transparent way on Linux

[Yves Rutschle]

Hello everyone,

To confirm I understood this right, I can supress all the
instructions in doc/config.md from line 124 to 185, and
replace them with just:

>     ip -6 rule add from ::1 lookup 100
>     ip -6 route add local ::/0 dev lo table 100

> ip rule add from 127.0.0.1 lookup 100
> ip route add local 0.0.0.0/0 dev lo table 100

Is that correct?

Cheers,
Y.
