Diagnose IPsec Tunnel Issues

Descripción de la oferta
My site-to-site IPsec tunnel was built following best-practice guides, yet the link keeps dropping for reasons I can’t see. The firewall on my side is an Opnsense appliance, and each time the tunnel fails the logs simply show that the connection drops intermittently without any clear error codes. I may have tweaked something recently, but I’m honestly not sure which setting—so I need a fresh, expert pair of eyes. You should be comfortable working with Opnsense and, ideally, have experience on Checkpoint or other enterprise firewalls so you can think through the usual Phase 1 / Phase 2, NAT-T, lifetime, and crypto-profile culprits quickly. I can give you full access to the existing configuration, live logs, and packet captures through a remote session. The job is complete when you: • identify the root cause of the dropouts, • apply and document the corrective changes, and • confirm the tunnel stays up under sustained traffic. If additional monitoring or rule cleanup is required, let me know and we can extend the scope. Looking forward to having this link rock-solid again.
