Hi Martin182,

tmm --clientciphers allYou can use the "!DHE:!DH" string to remove DHE and DH key exchange parameters from the cipher suite. Or you can use only "ECDHE+AES-GCM" cipher suite.
Just check your ssl config, there is a cyhper config hidden under a Basic/advanced filter in the profile that might not be fully locked down.
I had something very simular. in v14. and it was more on the ssl config than what was supported.

You mean the cipher rules/groups?, they are not available on this version, I think the first one to implement them is v13.
O, sorry i started my f5 works at late v13 straight into v14 about 2 months later.
So it looks like its a feature that's appeared in that time!
