Video Games and OPNSense - Rainbow Six Siege

Is there a decent way that someone knows of to test that my port forwarding rules are correct? Canyouseeme and other such tools only seem to work for TCP and only if an application is listening on that port.

Yes tcpdump. It needs to be run from the OPNsense shell but it will show you what is being blocked or passed. I'm currently using OpenBSD as my firewall so I can't test OPNsense port forwarding.

Reference port forwarding, don't set a specific destination IP just set it to any for testing purposes. Also your outbound port settings are very important. Provide a screenshot of your outbound port settings as well.

Your UPNP capure shows no configuration for IP's to allow access, and the default deny rule isn't selected.

Here are my captures (for consoles in CDIR range 192.168.0.80/29):

- UPNP settings
- Firewall showing UPNP and multicast
- NAT outbound hybrid with UPNP rule.
