Subjectraw socket packet and iptables
Hi, All,

I want to know how a raw packet passes the chain of iptables.

Here are the iptables chains

--->PRE------>[ROUTE]--->FWD---------->POST------>
Conntrack | Filter ^ NAT (Src)
Mangle | | Conntrack
NAT (Dst) | [ROUTE]
(QDisc) v |
IN Filter OUT Conntrack
| Conntrack ^ Mangle
| | NAT (Dst)
v | Filter


So how a raw packet go through these chains?

Thanks!!

Xinwen Fu
