leftsourceip should be set to the LAN IP of the machine that is
running Openswan - your gateway.<br>
Does 10.128.0.2 exist?<br>
I wonder if you have a firewalling problem but I'm not good with
these.<br>
<br>
I don't understand the question of bridging IPsec or OpenVPN
networks. It uses IPsec to bridge two networks. Similarly you can
use OpenVPN to two bridge networks.<br>

<div>Bascialy there are two networks <a

</div>
<div>Finally I managed (with your help) to set
up the site-to-site connection to my VPN
provider. Ipsec status shows that tunnel is
up:</div>
