Hi Brad,

 

Apologies if I didnt get your above reply, my query was that I want to set the ciphers in the order that the the Ciphers which offer PFS should come first and than the ones which don't offer PFS. So is it possible to do this on F5? does your above reply show the ciphers set in the same order that the ciphers which order PFS are placed first and the ones which don't offer this are placed below??
