Package: fiaif
Version: 1.20.1-2
Severity: important
Hi,
I'm running an openswan gateway for quite a long time now.
I have used 2.4.X and 2.6.X kernels without any problem until i decided
to upgrade to 2.6.16 kernel.
Summary of problem:
Under 2.6.15 everything is fine
Under 2.6.16 my tunnels establish well, but i can't even ping a single
computer located on the other end of the tunnel when the firewall is up.
Disabling the firewall solves the problem (but is not an option for me).
$ cat ip_conntrack | grep 192.168.10
icmp 1 8 src=192.168.0.192 dst=192.168.10.1 type=8 code=0 id=793
packets=4 bytes=116 [UNREPLIED] src=192.168.10.1 dst=XXX.XXX.XXX.XXX
type=0 code=0 id=793 packets=0 bytes=0 mark=0 use=1
192.168.0.0/24 is my lan subnet (natted so that lan computers can access
the internet through the public ip address)
192.168.0.192 is a workstation on my lan
192.168.10.0/24 is the other subnet
XXX.XXX.XXX.XXX is my public ip address
If i disable the nat of 192.168.0.0/24, i can ping the other end.
Re-enabling the nat however disables the ability to ping the other end.
Seems iptables is trying to nat packets the wrong way :$, or that I
missed a major change in 2.6.16.
*******************************************
Here is the answer from the kernel team:
No, it isn't a normal behaviour.
Patrick Mchardy ipsec patches were integrated in 2.6.16 and now
netfilter properly sees both esp & clear packets. This is a
drawback of your firewall/snat rules.
Adding it to fiaif.conf solves the problem (post start script):
iptables -t nat -I POSTROUTING -s 192.168.0.0/24 -d 192.168.10.0/24 -j ACCEPT

Ok, I am closing this. If there are still problems with newer kernels or
ipsec, please file a new bug report.
Thanks,
Bastian
