| Known bugs: | |
| 1) NAT in the OUTPUT chain does not work in general. The fix is | |
| intrusive, and means we will have a CONFIG_NF_IP_NAT_LOCAL option | |
| when it comes back. | |
| 2) tcpdump traffic is corrupted by OUTPUT NAT. | |
| 3) Connection tracking doesn't wait very long for reply FIN, meaning | |
| that half-closed pipes can time out early (seen frequently with squid). |
