Ciphers on profiles

Hi!

 

Maybe this is stupid question, but I need to know if a virtual server, with ssl server and client profiles, would have any issue if on the ssl client profile uses a particular cipher (let's say TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA) and on the ssl server profile uses other cipher (also let's say TLS_RSA_WITH_AES_128_GCM_SHA256.)

 

On the client profile is using a cert issued by a CA, and the server (the real one) is using a self-signed cert (the server profile is ignoring this.) SSL renegotiation is disabled using iRule on the virtual server.

 

Thank you in advance.

    There is no problem with that, actually is quite common. You can expose to the customer a strong clientssl profile where you enforce the most secure cipher string and in the server side as it may be consider a secure environment you can relax that policy by enforcing less consuming ciphers on your serverssl profile. Remember BIG-IP is a full proxy which means that client and server sides are different connections and that gives you a lot flexibility.
