Anyone has experience with level 4 switch ? What is the working principle of a level 4 in respect to redirecting web traffic to a cache engine ? Does it do dst IP address rewrite ( iptables DNAT ) or does it do dst MAC address rewrite ( ebtables dnat ) when redirecting traffic to the cache engine ?
Can I simulate a level 4 switch behaviour using Linux ? If yes, any insight to the necessary ebtables/iptables rules ?
