<p class="MsoNormal">Hi,</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-GB">I have a question regarding site-to-site vpns with vti interfaces.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">On my Debian Backports box i have several site to site vpns, some of them route based with GRE encapsulation using already configured tunnel interfaces. I have Quagga running for OSPF and routing and shorewall for iptables
configuration. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I want to create a new site-to-site VPN but this time instead of using GRE i want to route traffic using vti interfaces (im on kernel 3.16).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I went through the route-based vpn documentation here
<a href="https://docs.strongswan.org/strongswan-docs/5.9/features/routeBasedVpn.html#_gre">
https://docs.strongswan.org/strongswan-docs/5.9/features/routeBasedVpn.html#_gre</a> and it mentions that i have to configure charon.install_routes = 0 to disable route installation by the IKE daemon.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Would that have any effect on the rest of my tunnels? What does disabling route installation by the IKE daemon means exactly in this case and why is it needed?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Thanks.<o:p></o:p></span></p>
