Known bugs:
-1) NAT in the OUTPUT chain does not work in stock kernels. However,
- there is a patch in patch-o-matic, called the 'local-nat.patch'.
- This patch adds a CONFIG_NF_IP_NAT_LOCAL kernel config option.
+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.
