Hello,
I have configured a site to site vpn and tunnel is up but remote
network is unreachable.
Openswan version: 1:2.6.28+dfsg-5+squeeze2
kernel: 2.6.32-5-amd64
My side is debian linux firewall:
Public IP: xxx.xxx.xxx.xxx
Gateway: xxx.xxx.xxx.gw
Private IP: 192.168.5.12
The other side is a Cisco-ASA 5510:
Public IP: yyy.yyy.yyy.yyy
Private Network: 192.168.13.0/24
Here is my configuration file:

some eroutes exist
Traceroute shows that traffic is going to the Internet, not through the
tunnel. These are the firewall rules:
## VPN
iptables -A INPUT -p udp --dport 500 -j ACCEPT

Can someone help me with this issue?
Thank you,
