I have linux kernel 2.4.31 and Linux Openswan 2.4.4 (klips)

I have 2 tunnel , one tunnel is a winxp <---> linuxbox
                  two tunnel is a linksys <---> linuxbox

All tunnel is going up with no problem, the connections is up and running 
but :

The linux box see e use all machine and all service (netbios or apache) in 
the linksys network but the linksys network can't use any machines or 
services in the linux box network.
The strange is that the linksys network can ping some machine on the linuxbox 
network some but not all. NO firewall is up in other network

The winxp is = . the winxp can ping all machine in the linuxbox gatway but 
can use any services.

My configurations in the linuxbox is:

echo '1' > /proc/sys/net/ipv4/icmp_echo_ignore_all
echo '1' > /proc/sys/net/ipv4/icmp_echo_ignore_broadcast
echo '1' > /proc/sys/net/ipv4/icmp_ignore_bogus_error_responses
echo '0' > /proc/sys/net/ipv4/tcp_ecn

the ipsec.conf is :

version 2.0
