<p class="MsoNormal">Hello!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am trying to set up an IPv6 IPsec LAN to LAN tunnel between a linux system running strongSwan and a Cisco router.<o:p></o:p></p>
<p class="MsoNormal">I know that IPv4 multicast doesn’t work over IPsec, you need to add tunneling such as GRE. There is also the forecast plugin.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However, since IPv6 supports IPsec in the extension headers, it can natively support IPv6 multicast.<o:p></o:p></p>
<p class="MsoNormal">Can strongSwan running in IPv6 mode support IPv6 multicast, or do I still need to set up a tunnel?<o:p></o:p></p>
<p class="MsoNormal">Does the forecast plugin work in this case?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Another possibility is to use VTI. Someone got VTI to work with strongSwan, though there is no documentation, just an email thread.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am relatively new to IPsec and multicast, so I would really appreciate some guidance on this one.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
