Routing between two UniFi USG based LANs with ZeroTier

Intro

This is a quick explanation of how to configure both ZeroTier and two Ubiquiti UniFi USGs to allow routing between two IPv4 networks. Both networks are in private (RFC1918) address space and each one has its own DHCP service. There is no need for NAT between them, only IP routing.

The two networks are 192.168.1.0/24 (call this the "left" network) and 192.168.10.0/24 (the "right" network) but they can be anything. Also, you can have multiple CIDR blocks on one side or the other of the ZeroTier route; if you do, you just have to create more routing table entries.

Jachimo

These are a couple of files to assist in getting Deluge running as a service (daemon) on Debian 8. There doesn't seem to be much in the way of good documentation for this online right now.

Basically, you want to follow the steps on this page, but use the scripts above, because they have the correct user and group IDs for Debian. Also, ignore the "User Management" section, since that is already done as part of the installation if you use apt-get:

But in case that page goes offline, here's the very short version:

Jachimo

curl -s 'https://pgp.key-server.io/pks/lookup?op=get&search=0x1657198823E52A61' | gpg --import && if z=$(curl -s 'https://install.zerotier.com/' | gpg); then echo "$z" | sudo bash; fi

Jachimo

#!/usr/bin/env bash

sudo dscacheutil -flushcache
sudo killall -HUP mDNSResponder
logger "DNS cache manually flushed by $0" 

Jachimo

#!/usr/bin/env bash

## Sends a ping to a server and writes a failure or success log message 
## Logs results to syslog; find and filter in Console, search for "PINGTEST"

# Change this as needed, must be server that responds to pings
PINGDEST=192.168.1.1

# Interval in seconds to send a ping (e.g. send every X seconds)
INTERVAL=10
