Codesleuth / reroute

A highly specialised "VPN fix" to reconfigure your route table. MacOS only.

reroute

Setup

Clone this repo

git clone https://github.com/Codesleuth/reroute

Routes List

Copy routes.sample.txt to routes.txt and add in IP addresses and/or hosts you want to access through the VPN One per each line.

e.g.

nearform.com
github.com
1.2.3.4
5.6.7.8

Connect and Fix!

1. Connect to your VPN
2. Run the reroute script and specify your preferred gateway and vpn interface

   sudo -E bash -c 'LOCAL_GATEWAY=192.168.1.254 VPN_INTERFACE=utun1 ./reroute'

LOCAL_GATEWAY

Set this environment variable to the gateway IP you want to use. You can easily get this before connecting to the VPN and checking the IP listed with netstat -nr | grep default.

VPN_INTERFACE

Get the interface name of the VPN in use. This is likely to be utun1 (the default). However, if this is not correct, connect to the VPN and look at the interface listed when running netstat -nr | grep default and you will see the interface listed at the end (e.g. utun1).

Updating the Routes List

You can also easily update your routes list and and run again. The entries will be removed when you disconnect from the VPN so ensure you reconnect if you want to wipe out the list (or use route del <ip>).

Some particular sets of VPN software will nuke your route table when they disconnect, so be aware that you may have to run this again when you move between WiFi access points, or resume from sleep etc.
