For Directories:

Run commands in Synology

1. Download cloudflareddns.sh from this repository to /usr/local/sbin/cloudflaredns.sh

wget https://raw.githubusercontent.com/joshuaavalon/SynologyCloudflareDDNS/master/cloudflareddns.sh -O /usr/local/sbin/cloudflaredns.sh

If you put the script in other name or path, make sure you use the right path.

2. Give others execute permission

chmod +x /usr/local/sbin/cloudflaredns.sh

3. Add cloudflareddns.sh to Synology

cat >> /etc.defaults/ddns_provider.conf << 'EOF'
[Cloudflare]
        modulepath=/usr/local/sbin/cloudflaredns.sh
        queryurl=https://www.cloudflare.com/
EOF

queryurl does not matter because we are going to use our script but it is needed.

Get Cloudflare parameters

1. Go to your domain overview page and get the Zone ID.
2. Go to your account setting page and get API Key.
3. Get record id using Cloudflare API.

curl -s GET "https://api.cloudflare.com/client/v4/zones/[Zone ID]/dns_records" \
	-H "X-Auth-Email: [Email]" \
	-H "X-Auth-Key: [API Key" \
	-H "Content-Type: application/json" \
	| jq '.result[] | {name, id, zone_id, zone_name, content, type}'

You need to replace with [] with your parameter. Then, you get the id in result which is you Record ID.

Setup DDNS

1. Enter the parameters to the cloudflareddns.sh.
2. Login to your DSM
3. Go to Control Panel > External Access > DDNS > Add
4. Select Cloudflare as service provider. Enter your domain as hostname, your Cloudflare account as Username/Email, and API key as Password/Key

Till now, there is no official iOS app to add/manage torrent tasks of TransmissionBT. The only working application is iControlbits which is available to Jailbroken iOS users.
So there is not much choice left for non-jailbroken users to manage Tranmission tasks. We can use Safari web browser to view and delete the downloading task but no way to add torrent file as iOS has a very strictly privilege control on file dealing. It is impossible to download a torrent file and upload it via Safari browser.
