| This is IPv6 support on Layer 3 independent connection tracking. |
| Layer 3 independent connection tracking is experimental scheme |

| help |
| Masquerading is a special case of NAT: all outgoing connections are |
| changed to seem to come from a particular interface's address, and |
| if the interface goes down, those connections are lost. This is |
| only useful for dialup accounts with dynamic IP address (ie. your IP |
| address will be different on next dialup). |
