Anyone? We are looking for 10G solutions as well. Currently, we are running Cisco 6500 series with FWSM for NAT Translations, and SUP720 3BXL. We are looking at Mikrotik as options before we upgrade to all an all Cisco solution.
You need to realize that with hardware accelerated stuff everything is fine until your configuration āfitsā into available features, as soon as you need something outside the provided set of features you are screwed.
I had experience with other equipment that provided hardware NAT acceleration, all look beautiful until problems started - in the end it turns out hardware NAT supported only 1000 connectionsā¦
Statement about 1Gbps TCP it is only for 1 TCP connection, iām pretty sure that qwith 10G connection you will have much more tht 1 TCP connection .
in any case i will have to agree with previous poster - āNAT with 10G connectionā is not enough information to answer your question. We need to know full set of features you plan to use and actual max available traffic to provide some educated guess.
