ipsec and/or netfilter problem
From: Kiko Piris

Hi,
I've set up ipsec in my home LAN, it works like a charm except for a
little problem.
First, let me explain my network topology. It's a LAN [10.12.0.0/18]
with one server [10.12.0.1] and 2 workstations (one desktop [10.12.1.1]
and a laptop [10.12.1.2 and 10.12.2.2]).
The server has 3 NIC's: eth0 which is connected to the internet with my
cable ISP and br0 (a bridge of eth1 and wlan0) that's connected to the
LAN.
The server does SNAT (MASQUERADE) on eth0 to allow the workstations to
connect to the Internet.
My goal with ipsec is to secure all the LAN traffic (both ethernet and
wireless) so that all traffic is encrypted and authenticated.
The only problem I have is securing the traffic that the workstations
send to Internet. I define the following security policy:
At the server:
| spdadd 0.0.0.0/0 10.12.1.1 any -P out ipsec esp/tunnel/10.12.0.1-10.12.1.2/require;
| spdadd 10.12.1.1 0.0.0.0/0 any -P in ipsec esp/tunnel/10.12.1.2-10.12.0.1/require;
At the workstation:
| spdadd 10.12.1.1 0.0.0.0/0 any -P out ipsec esp/tunnel/10.12.1.1-10.12.0.1/require;
| spdadd 0.0.0.0/0 10.12.1.1 any -P in ipsec esp/tunnel/10.12.0.1-10.12.1.1/require;
It's doing the expected thing: tunnel all traffic from workstations to
Internet through ipsec up to the server.
The problem is that the server sends the data to Internet without doing
SNAT (checked with tcpdump) (the packets do not traverse the POSTROUTING
chain in nat table, checked watching the pkts counters).
These are the rules I've got at the nat table:
| root@server # iptables -vnL -t nat
| Chain PREROUTING (policy ACCEPT 132K packets, 7676K bytes)
| pkts bytes target prot opt in out source destination
| 0 0 DNAT udp -- eth0 * 0.0.0.0/0 0.0.0.0/0 udp spts:1024:65535 dpt:27960 to:10.12.1.1
| 0 0 DNAT udp -- ppp0 * 0.0.0.0/0 0.0.0.0/0 udp spts:1024:65535 dpt:27960 to:10.12.1.1
|
| Chain POSTROUTING (policy ACCEPT 12968 packets, 1278K bytes)
| pkts bytes target prot opt in out source destination
| 2433 147K MASQUERADE all -- * eth0 10.12.0.0/16 0.0.0.0/0
| 0 0 MASQUERADE all -- * ppp0 10.12.0.0/16 0.0.0.0/0
| 0 0 MASQUERADE all -- * br0 10.12.0.0/16 192.168.1.0/24
|
| Chain OUTPUT (policy ACCEPT 12736 packets, 1142K bytes)
| pkts bytes target prot opt in out source destination
I've tried to use NAT_LOCAL but when I issue the iptables command I get
an error:
| root@server # iptables -t nat -A OUTPUT -s 10.12.0.0/16 -o eth0 -j MASQUERADE
| iptables: Invalid argument
| root@server # iptables -V
| iptables v1.2.9
| root@server # uname -a
| Linux bacterio 2.6.8-rc2 #1 Mon Jul 26 17:54:31 CEST 2004 i686 GNU/Linux
Kernel config @server is attached.
Anyone has any hint?
If this is not the right list to post this kind of things, where should
I ask?
Many thanks in advance
