SSL Client profile - OPTIONS question??

 

I have been experimenting with custom ClientSSL Profiles with minimal success. Can someone please tell me the syntax for forcing the LTM to allow connections only with this cipher suite:

 

 

TLS_RSA_WITH_RC4_128_MD5

 

 

I am assuming the correct syntax just needs to go in the options field or at least that's what I've been doing. I chose this one because this is what my browser connects at and it works but the custom app does not work.

 

 

Any help is fully appreciated.

 

 

Thank you,

    Take a look at SOL8802 and SOL7815 for details on the SSL cipher suites available:

    You may also want to handle non-compliant requests more gracefully by checking the cipher strength in an iRule
