A simple [procd](https://openwrt.org/docs/techref/procd)-based ```vpnbypass``` service for OpenWrt/LEDE Project. This is useful if your router accesses Internet through a 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.
- Define local ports so traffic to them is routed outside of the VPN tunnel (by default it routes Plex Media Server traffic (port 32400) outside of the VPN tunnel).
- Define IPs/subnets in local networks so their traffic is routed outside the VPN tunnel (by default it routes traffic from 192.168.1.81-192.168.1.87 outside the VPN tunnel).
- Define remote IP ranges that are accessed outside the VPN tunnel (by default, LogmeIn Hamachi traffic (25.0.0.0/8) is routed outside the VPN tunnel).
- Creates list of domain names which should be accessed outside the VPN tunnel (useful for Netflix, Hulu, etc).
- Does not reside in RAM -- creates `iptables` rules which are automatically updated on WAN up/down events.
- A companion package (`luci-app-vpnbypass`) is provided so all features may be configured from the Web UI.
- Proudly made in Canada, using locally-sourced electrons.

## Default Settings
Default configuration has service disabled (use Web UI to enable/start service or run ```uci set vpnbypass.config.enabled=1; uci commit vpnbypass;```) and 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 192.168.1.81-192.168.1.87 outside of the VPN tunnel. You can safely delete these example rules if they do not apply to you.
The default configuration ships with the service disabled, use the Web UI to enable/start the service or run ```uci set vpnbypass.config.enabled=1; uci commit vpnbypass;```. It routes Plex Media Server traffic (port 32400) and LogmeIn Hamachi traffic (25.0.0.0/8) outside of the VPN tunnel. Internet traffic from local IPs `192.168.1.81-192.168.1.87` is also routed outside the VPN tunnel. You can safely delete these example rules if they do not apply to you.

### Bypass Domains Format/Syntax
Domain lists should be in following format/syntax: ```/domain1.com/domain2.com/vpnbypass```. Please don't forget the leading ```/``` and trailing ```/vpnbypass```. There's no validation if you enter something incorrectly -- it just won't work. Please see [Notes/Known Issues](#notesknown-issues) if you want to edit this setting manually, without Web UI.

- Table ID, IPSET name and FW_MARK as well as FW_MASK can be defined in config file.
- Uses iptables, not ip rules for handling local IPs/ranges.
- More reliable creation/destruction of VPNBYPASS iptables chain.
- Updated Web UI enables/start and stops service.
- Updated Web UI enables, starts and stops the service.
## Notes/Known Issues
1. Domains to be accessed outside of VPN tunnel are handled by dnsmasq and thus are not defined in ```/etc/config/vpnpass```, but rather in ```/etc/config/dhcp```. To add/delete/edit domains you can use VPN Bypass Web UI or you can edit ```/etc/config/dhcp``` manually or run following commands:
