I had some problem when installing SSL to Barracuda 340 load balancer.
When I installed a SSL certificate and key with Barracuda web UI.
I specified the SSl key and certificate and intermediate certificate as below.
Barracuda rejected my certificates.I didn't know why and tried it many times.but Barracuda still kept rejecting.:( I hated the red strings on that.
After desperating it,I googled related issues with Barracuda and found some article in Barracuda support website.Solution #00001327
When you have some problems with SSL installation to Barracuda load balancer,try to write the certificate and intermediate certificate into 1 file.
like following
-----BEGIN CERTIFICATE----- <---- some domain's certificate
