Big-F5 loadbalancer with apache web for SSL

Configure Apache and F5 loadbalancer.

 

We are facing some issue while configuring the SSL between F5 and Apache.Our flow is

 

Client(SSL) ->F5 (SSL drops )->(recreate ssl to apache layer)->Apache webserver. 1) Create CSR from apache web layer,get sign as trusted from the company(not external). 2) configure in ssl.conf and ciphersuite Now initiate a request using openssl it is throwing

 

depth=1 DC = net, DC = racb, CN = XXXXXX CA 1 verify error:num=20:unable to get local issuer certificate read from 0x1b9c8d0 [0x1ca04f3] (5 bytes => 5 (0x5))

 

IN order to verify i modified the /etc/hosts entry as xxx.xxx.xxx.net as 127.0.0.1 and move the chain certificate to /etc/pki/ca-trust/source/anchor and update-ca-trust extract

 

and run the openssl which is return with error code =0 and waiting in SSL session.

 

What mistake we are doing in F5 no idea.Can someone throw the lights
