I have a brand-new 3CX PBX that sits behind an OPNsense firewall (latest stable release) on a static public IP. Before I put the system into production I need the proper NAT and firewall rules created so that every test in the 3CX Firewall Checker reports “pass”. The job is straightforward: connect remotely to the OPNsense UI, create the required port forwards and any supporting rules, confirm SIP-ALG is not interfering, apply the settings, then run the 3CX checker with me on the call until it shows green across the board. Please work directly on the appliance—no exported configs—so changes take effect immediately. I will supply temporary administrator credentials and an out-of-band reboot option if needed. Deliverables • OPNsense configured with all ports/services 3CX requires • Confirmed passing result in 3CX Firewall Checker • Brief note of what was changed so I can document it internally Success is measured solely by the checker passing and external calls registering correctly.
