Hi,

I would like to establish an IPSEC connection from one site to one site.
Site A is a Cisco ASA and site B is a Linux Debian Wheezy

On site A we don't have any access, but on site B we can do what we want.
I installed Shorewall 4.5.5.3 and openswan 1:2.6.37-3+deb7u1

I spent a lot of time trying to connect those 2 sites like this

site B                                                                          
 site A
[ 10.1.0.0 ] -----[ 10.1.0.1 / eth0 143.123.123.121/28 ] ..... [ 190.120.87.165 
]---[193.198.43.0]
                               eth0 143.123.123.122

This would be relatively simple if Site A did not want nat in the VPN. In fact 
they want to see only one source address from the network B for example
the 143.123.123.122. They don't want to see rfc1918 addresses in subnet B.

I read and reread the pages of shorewall but I'm a little bit confused now.
I can establish IPsec phase I but the second not. Ipsec therefore works but it 
appears that phase II stuck.

My part of config:

interfaces
vpn     ppp0    -
net     eth0

hosts
vpn     eth0:193.198.43.0/24   ipsec

masq
eth0    10.1.0.0/24     143.123.123.122  -       -       -       
mode=tunnel,tunnel-dst=193.198.43.0/24

tunnels
ipsec   net       190.120.87.165/32       vpn

Many thanks in advance for you help and lights ....
