Proxying the update host for Eurolan STBs

Firmware updates for TH100/TH200/TH300 set-top boxes are served from stb.xakcop.com:443. If this host is not reachable from your internal IPTV network, then you can setup a proxy update host:

+------------+           +--------------+           +--------------------+
|            |           |              |           |                    |
| TH100 STBs |<--------->| Proxy Update |<--------->| stb.xakcop.com:443 |
|            |           |     Host     |           |                    |
+------------+ +--------------+ +--------------------+

#  Simple HTTP server that  supports file upload  for moving data around
#  between boxen on HTB. Based on a gist by bones7456, but mangled by me 
#  as I've tried  (badly) to port it to Python 3, code golf it, and make
#  It a  little more  robust. I was also able to  strip out a lot of the 
#  code trivially  because Python3 SimpleHTTPServer is  a thing, and the
#  cgi module handles multipart data nicely.

Connecting TH-100 STBs to Wireguard VPN server

This guide shows how to connect TH-100 STBs to a Wireguard VPN server. On the server side you need a Linux box with Wireguard installed. For Debian/Ubuntu simply run:

$ sudo apt install wireguard
$ sudo sysctl -w net.ipv4.ip_forward=1

Your TH-100 STBs needs to run firmware version 286 or later.
