[2.5] ipsec + iptables

Hi *,

Is there any documentation on how the new 2.5 ipsec plays together with itables? How do ipsec packets traverse the tables? Where is the encryption/decryption of the packets done? In transport mode? In tunnel mode?

The freeswan documentation is quite clear about this: For example incoming packets: The paket filters see the packets twice: Once from the physical device (eth0, ppp0, whatever), with data still encrypted and protocol 50/51, and once from the attached virtual ipsec<n> device, after decryption in cleartext (so iptables actually sees what tcp/udp port it is addressed to, ...).

How does the new ipsec code work compared to that? Probably different as there is no virtual ipsec<n> device any more, but how exactly?
