I just purchased a Kobo Sage, and I'm looking at using the built-in web browser to access a few services that are only accessible on my local network. I use Tailscale (which is essentially Wireguard) which uses the mainline TUN/TAP driver from the Linux kernel.
Do modern Kobo's (based on the 4.9+ kernel) include the TUN/TAP driver/kernel module? If not, is that something that's relatively easy to compile and load in manually?
Alternatively, Tailscale supports user-mode networking via a SOCKS5 proxy.
The Kobo Configuration Options page lists a "proxyUrl" configuration. Can I use this to connect to the locally-running SOCKS5 proxy and have the built-in web browser use that proxy?
