18 | Connection tracking keeps a record of what packets have passed | |
19 | through your machine, in order to figure out how they are related | |
20 | into connections. | |
21 | ||
22 | This is IPv6 support on Layer 3 independent connection tracking. | |
23 | Layer 3 independent connection tracking is experimental scheme | |
24 | which generalize ip_conntrack to support other layer 3 protocols. | |
