Re: CSS backend SSL

The certificate is associated to a website (ie: www.cisco.com)

The same certificate can then be installed on all required devices.

So, you only need 1 cert from verisign.

Backend-ssl is not required unless you do not trust the link between css and servers.

You could simply have HTTP between CSS and servers (this is the most common practice).

Usually banks require backend-ssl because they have to guarantee end-to-end encryption.

ssl-server 20 cipher rsa-with-rc4-128-md5 192.168.7.101 81

This means your traffic is decrypted and sent to 192.168.7.101:81

This is normally another VIP where you do backend ssl.

So, I feel like your config is incorrect.

Under

owner KIB-SSL

content SSL-BACKEND

vip address 192.168.201.100

The vip is incorrect.

It should be 192.168.7.101
