Hi, we have been using opnsense for around four years. We use them to create a vpn from each of our sites to azure WANHub. This has worked without issue until started updating our ipsec VPNs earlier this year, as the old method was being deprecated. Since then we have had constant issues. For example today a site that has been working without issue for several weeks suddenly dropped connection. Restarting the VPN service will appear to connect, and will show as connected in the WANhub but we only see traffic in one direction. Nothing has been changed we see no blocked traffic. Often a reboot will resolve the issue. The new method of ipsec is different to the old method in term of automatic firewall rules etc and we have taken account of those. But each time I think I have found a fix and everything is working a few weeks later the site drops. Be interesting t know if anyone else uses Azure WAN and if they have had issues. A case in point the site that went down about 30 minutes ago is now re connected and I have no idea why.
