I have two corporate offices running FortiGate appliances that must be linked through a reliable site-to-site tunnel. The goal is to configure both ends so traffic flows seamlessly while meeting our security standards. Here is what I need from you: • Configure the tunnel on each FortiGate using IPsec with the option to leverage SSL/TLS where appropriate for added hardening. • Optimise phase-1 and phase-2 parameters (encryption, hashing, lifetime) to balance security and performance. • Define the policies and routes so internal subnets at both offices communicate bidirectionally without hair-pinning or bottlenecks. • Provide a brief step-by-step document or screenshots so I can replicate the setup if hardware is replaced. Both devices are already online and reachable via FortiOS GUI and CLI; I can supply admin credentials and current firmware details once we start. Remote access will be through my preferred screen-sharing tool or SSH, whichever you prefer. I’ll consider the job complete when traffic passes both ways and the connection survives a reboot of either firewall. If you have deep Fortinet experience and can wrap this up quickly, let’s get it done today.
