Hi, I'd like to know whether F5's can do the following. I have two servers I want to keep in sync (see exactly the same traffic) they must be seen as one machine from the outside world. So they would both receive the same data, and both reply, but the reply from only one would be sent to the client. I am not sure about the technical terms for all this, I am a newbie. Also the F5's would have to be redundant, so if one failed the other would take over seamlessly. If one of the servers fails the F5's would detect this and keep the connections going so the outside world wouldn't know that anything had happened.
