vpnbypass: HOTFIX no longer incorrectly stopping service/reliable start
fixed: stop function used to kill the hotplug file
fixed: despite ubus wait_for network.interface.wan and WAN-IF hotplug, sometimes we'd get no WAN ip on start

A simple PROCD-based vpnbypass init script for OpenWrt/LEDE Project. Useful if your router accesses internet thru VPN client/tunnel, but you want specific traffic (ports, IP ranges, domains or local IP ranges) to be routed outside of this tunnel.
# Features
- Routes Plex Media Server traffic outside of the VPN tunnel.
- Allows you to define IPs/ranges in local network so that their traffic is routed outside of the VPN tunnel.
- Allows you to define list of domain names which are accessed outside of the VPN tunnel (useful for Netflix, Hulu, etc).
# OpenWrt VPNBypass
A simple PROCD-based vpnbypass service for OpenWrt/LEDE Project. Useful if your router accesses internet thru VPN client/tunnel, but you want specific traffic (ports, IP ranges, domains or local IP ranges) to be routed outside of this tunnel.
## Features
- Allows to define local ports so that traffic to them is routed outside of the VPN tunnel (by default routes Plex Media Server traffic (port 32400) outside of the VPN tunnel).
- Allows to define IPs/subnets in local network so that their traffic is routed outside of the VPN tunnel (by default routes traffic from 192.168.1.81-192.168.1.87 outside of the VPN tunnel).
- Allows to define remote IPs/ranges that they are accessed outside of the VPN tunnel (by default routes LogmeIn Hamachi traffic (25.0.0.0/8) outside of the VPN tunnel).
- Allows to define list of domain names which are accessed outside of the VPN tunnel (useful for Netflix, Hulu, etc).
- Doesn't stay in memory -- creates the iptables rules which are automatically updated on WAN up/down.

- Has a companion package (luci-app-vpnbypass) so everything can be configured with Web UI.
- Proudly made in Canada, using locally-sourced electrons.
# Requirements
This service requires following packages to be installed on your router: ip-full ipset iptables dnsmasq-full (dnsmasq-full requires you uninstall dnsmasq first). Run the following commands to satisfy the requirements:

This service requires following packages to be installed on your router: ip-full ipset iptables dnsmasq-full (ip-full requires you uninstall ip first; dnsmasq-full requires you uninstall dnsmasq first). Run the following commands to satisfy the requirements:
Default install routes Plex Media Server traffic (port 32400) outside of the VPN tunnel, routes LogmeIn Hamachi traffic (25.0.0.0/8) outside of the VPN tunnel and also routes internet traffic from local IPs 192.168.1.80-192.168.1.88 outside of the VPN tunnel.

You can safely delete these example rules if they do not apply to you.
