| Known bugs: |
| |
| 1) NAT in the OUTPUT chain only works since kernel 2.4.18. However, |
| there is a patch for previous kernels in patch-o-matic, called the |
| 'local-nat.patch'. This patch adds a CONFIG_NF_IP_NAT_LOCAL kernel config |
| option. |
| |
| 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). |
| |
| 4) When you use ip6tables packet mangling on IPv6 packets, the packet will |
| not be re-routed in case e.g. you insert a routing header. |
