Hi everyone. I have a plugin on my OPNsense instance to route the RTSP traffic that the ISP uses for the video on demand on the TV service. That plugin worked fine on v25.7 but on v26.1 it no longer works.
The plugin basically intercepts any request that goes from the TV to a given list of IPs on port 554, and then it configures the firewall to route the incoming video stream packets from the RTSP server to the TV.
Now on v26.1 the plugin is not able to intercept that requests, so in consequence it doesn't route the video stream from the server to the TV.
I saw on the change log that there are some major changes on the firewall, and I want to know how can I make to work that process of intercepting the packets and then configuring the firewall accordingly on v26.1.
Is that any plugin that is shipped here?
I can't find it in the list.

It's not. It was originally developed by someone else but I ended up taking that code, applying some fixes and installing manually on my machine. It has been doing its job since then. After upgrading from 25.7.11 to 26.1 it still worked in terms of not crashing, but it wasn't doing it's job because it can no longer capture the requests that the tv box sends to the RTSP server. I never submitted the plugin to the plugins repo because I think the code quality is not good enough to be used by someone else (I'm not a python dev, I fixed it just enough for it to work), but it was doing its job for me. I started using it with OPNsense 24 and it never failed or crashed. And as far I know there's no "compatibility mode" for the firewall on 26.1 that would allow me to continue using the plugin. Also on that plugins list I see that igmp-proxy is no longer maintained (I also use it). I'm a bit concerned that some future update will include a breaking change that will cause also igmp-proxy to stop working.
