IPv6 now faster than IPv4 when visiting 20% of top websites – and just as fast for the rest

Re: now just trollin

You write as if NAT doesn't exist on IPv6.

-t, --table table

This option specifies the packet matching table which the command should operate on. If the kernel is configured with automatic module loading, an attempt will be made to load the appropriate module for that table if it is not already there.

The tables are as follows:

filter:

This is the default table (if no -t option is passed). It contains the built-in chains INPUT (for packets destined to local sockets), FORWARD (for packets being routed through the box), and OUTPUT (for locally-generated packets).

nat:

This table is consulted when a packet that creates a new connection is encountered. It consists of three built-ins: PREROUTING (for altering packets as soon as they come in), OUTPUT (for altering locally-generated packets before routing), and POSTROUTING (for altering packets as they are about to go out). Available since kernel 3.7.

My god, what's that "nat" table doing there then?
