Question

Site to Site / Tunnel Between Fortinet and Sonicwall

Hello....

 

We created a site to site between a fortinet and sonicwall.  Added Policies on the fortinet.  VPN comes up but fortinet doesn't route traffic over VPN.  Hard coded a static route on the fortinet side and traffic flows as expected.  None of the documentation I found for fortinet mentions configuring the static route.  Are we missing a step or configuration task somewhere?

 

Thanks

    Hello,

     

    Static routes are required while configuring site to site IPsec. Please find an example by following the link below:

     

    https://docs.fortinet.com/document/fortigate/6.4.2/administration-guide/913287/basic-site-to-site-vpn-with-pre-shared-key

     

    Section "Configure the static routes. Two static routes are added to reach the remote protected subnet. The blackhole route is important to ensure that IPsec traffic does not match the default route when the IPsec tunnel is down."
