    <div text="#000000" bgcolor="#ffffff">left=privateip and right
=public ip is correct.<br>
and on your adsl router you have to make few rules like<br>
anything comming on router's public ip <br>
&nbsp;&nbsp;&nbsp; on UDP port 500 or port 4500 should be redirected to your vpn
server's private ip which is behind your adsl router
    <br>
&nbsp;&nbsp;&nbsp; and proto ESP should be redirected to your vpn server's private ip
which is behind your adsl router<br>
this are the rules you have to apply on both adsl routers.<br>
    <br>
eg. <br>
&nbsp;&nbsp;&nbsp; source=any<br>
&nbsp;&nbsp;&nbsp; destination=router1's public ip
    <br>
&nbsp;&nbsp;&nbsp; protocol UDP<br>
&nbsp;&nbsp;&nbsp; port 500/4500<br>
&nbsp;&nbsp;&nbsp; forward it to vpnserver1's private ip<br>
same way at other end<br>
    <br>
and i think on adsl router you might have facility to disable
passthrough of vpn or ipsec<br>
and can make a rule to redirect ipsec/vpn service to a desired
destination

&gt;<br>
&gt; I have to install the kernell natt patch??<br>
&gt;<br>
&gt; Could someone help me with ipsec.conf file? I've been searching

i have achieved above scenario with following changes it might not be<br>
perfect solution... <br>
on adsl router apply portforwarding rules for UDP port 500 port 4500 and<br>
proto esp(50) to your vpn server on both end<br>
            <br>
configure your ipsec.conf as below<br>
