Where do you enter that and why? What is the thing _you_ call a |
| 10 |
loopback? On what device or machine does it exist? You don't seem to be |
| 11 |
talking about the "ifup" tool (since you talk about "ip", which however |
| 12 |
does not know the "nat" mode?!?), and you don't seem to be talking |
| 13 |
about the lo device either. |

Errm, again: What? Setting up you loopback device on gentoo is done |
| 19 |
automatically by /etc/init.d/net.lo. Should be run on bootup by rc, |
| 20 |
check "rc-update show". |

Setting up NAT works using a sysctl (or the procfs). Restricting the |
| 23 |
NAT works using iptables. |

Errrr.... Again, not sure what you are asking here... Yes, you need |
| 28 |
kernel modules for both NAT to work and as well netfilter modules for |
| 29 |
the chains and targets and matches you want to use with iptables. They |
| 30 |
don't really have to be modules, you can compile them statically into |
| 31 |
the kernel as well. |
| 32 |
|
| 33 |
If unsure, rephrase your question -- and be a bit more verbose on what |
| 34 |
you intend to do... A bit more information might as well cure lack of |
| 35 |
proper vocabulary... Give examples, try to describe the setting. |
