Synology DiskStations

You can configure a Synology DiskStation with CloudFlare DDNS.

Step 1. Access Synology via SSH

• Login to your DSM
• Go to Control Panel > Terminal & SNMP > Enable SSH service
• Use your client or commandline to access Synology. If you don't have any, I recommand you can try out MobaXterm for Windows.
• Use your Synology admin account to connect.
• Run the following command to add new DDNS provider:

cat >> /etc/ddns_provider.conf << 'EOF'
[USER_Cloudflare]
        modulepath=/usr/local/sbin/cloudflareddns.sh
        queryurl=https://www.cloudflare.com/
E*.

Step 2. Install cloudflareddns

curl https://bootstrap.pypa.io/get-pip.py | python
pip install virtualenv
# create virtualenv twice to ensure creation of "activate" script
virtualenv /usr/local/CloudflareDDNS
virtualenv /usr/local/CloudflareDDNS
# go inside our virtualenv
. /usr/local/CloudflareDDNS/bin/activate
# install the packages we need there (cloudflare will be used in the future):
pip install cloudflareddns

Step 3. Get Cloudflare parameters

Go to your account setting page and get API Key.

Step 4. Setup DDNS

• Login to your DSM
• Go to Control Panel > External Access > DDNS > Add
• Select Cloudflare as service provider. Enter your domain as hostname, your Cloudflare account as Username/Email, and API key as Password/Key
