When it comes to network accounting the following may be of interest - |

Network accounting was demonstrated based on the ip_conntrack module in |
| 13 |
the kernel. Some new enhancements of ip_conntrack solve some problems |
| 14 |
you have with accounting in userspace with single ip_tables rules for |
| 15 |
each IP-Address or similar userspace solutions. You don't have the |
| 16 |
overhead of transfering huge amounts of data to userspace or getting |
| 17 |
endless rulesets as you have with previous approaches. |

Sorry, I did not use it myself and I don't know a link to further |

information, but searching for ip_conntrack may give some hints. |
