Has any one managed to use the free SSL provided Let's Encrypt to provide an SSL certificate for their ZoneDirector?

Model: ZD1200 Version: build 75

Prepare 3 key file from

3. private.key

Go to Configure ,  Certificate 
Go to Add a trusted CA and import "ca_bundle.crt".
Go to Import Signed Certificate and import "certificate.crt".
if certificate.crt is fine, you will be asked to import the "private.key" and reboot.

If you are using 2 ZoneDirector for HA, then you need to do it in both sides.

Problem is that you have to make and install new certificate every 3 month, as certificate expiration is 90 days -- so it doesn't make much sense for me...
Easier to pay once a 3 years for certificate and forget about it until next time. 
Hope it helps

Sorry to revive a long dead thread...

If you have an ACME client running on a router/server somewhere then you can probably push the Let's Encrypt certificates onto a ZoneDirector or Unleashed.

I've been using Let's Encrypt certificates on my home ZoneDirector for a few months now, via my pfSense firewall.

The steps to get it working on pfSense are documented at
