for a couple of days I am trying to set up a VPN site to site between my office (RV160) and remote branch (Fortigate), I completed all steps as mentioned in configuration guide but nothing work, I literally search everything on internet but nothing works! even the log massages not helpful at all. i did packet capture on other end (fortigate) but nothing received, seems the router didn't send any packet.
Its very simple topology I want to encrypt lan to lan traffic between two sites each site has public IP and perform PAT.
wondering if i miss any config related to NAT or any advise please.
