<p class="MsoNormal"><span style="font-family:"Cambria","serif"">Hi all,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Cambria","serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Cambria","serif"">I’m using Link local GRE tunnel, With source interface as eth1.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Cambria","serif"">I’m able to encrypt all the packets sent on eth1.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Cambria","serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Cambria","serif"">But I want only the packets , which are GRE and sent on Eth1 has to be encrypted.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Cambria","serif"">I added leftprototype=gre , rightprototype=gre in ipsec.conf file.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Cambria","serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Cambria","serif"">But the packets are not getting encrypted and ping also not working after this change.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Cambria","serif"">And also , I came to know that it got deprecated.<o:p></o:p></span></p>
<p><em><span style="font-size:11.0pt;font-family:"Cambria","serif"">left|rightprotoport = <protocol>/<port></span></em><span style="font-size:11.0pt;font-family:"Cambria","serif""><o:p></o:p></span></p>
<p><span style="font-size:11.0pt;font-family:"Cambria","serif"">restrict the traffic selector to a single protocol and/or port. Since
<a href="https://wiki.strongswan.org/projects/strongswan/wiki/510">5.1.0</a> this option is deprecated<br>
as protocol/port information can be defined for each subnet directly in <em><span style="font-family:"Cambria","serif"">left|rightsubnet</span></em>.<o:p></o:p></span></p>
<p><span style="font-size:11.0pt;font-family:"Cambria","serif"">Can you please point me , how to use the same in strongswan 5.3<o:p></o:p></span></p>
<p><span style="font-size:11.0pt;font-family:"Cambria","serif"">Thanks,<o:p></o:p></span></p>
