Hello, I understand you're having difficulties with your OPNSense 25.7.2 firewall's VPN connections. It sounds frustrating that Wireguard and OpenVPN are both giving you trouble, especially when you've already tried some adjustments like lowering the MTU and disabling hardware offload. My approach will be to thoroughly analyze both VPN setups, check your NAT and routing configurations, and investigate logs to pinpoint the issue causing those stalls and handshake failures. I will ensure that both Wireguard and OpenVPN are not only functional but stable, and I'll document any changes made to rules or parameters for easy reference in the future. I’m ready to dive in as soon as we set up remote access to your firewall. Can you provide specific details about any recent changes or updates made to the OPNSense system that might have affected VPN connectivity? Thanks, Muhammad Awais

Hi, I’m Engineer Antony—Freelancer since 2014 with 800+ reviews and 15+ years of deep Linux/networking expertise. I’ve worked extensively with OPNSense, WireGuard, and OpenVPN across edge-firewall deployments. I’ll dive into your setup remotely, trace what’s breaking WireGuard (likely MTU, route conflict, or stateful inspection edge case), and restore stable tunnels. Expect: robust config, packet-flow verified, and a documented change log (NAT, MTU, sysctls, etc.) to future-proof upgrades. I can schedule around your maintenance window and start triage within 24h. Bonus: I’ll include a shell-ready backup script so you can snapshot configs safely. Want me to check NIC driver/firmware as well?
