Unable to add unbridged camera unless I disable firewall (homebridge running on Synology)
### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe The Bug

I'm unable to add or stream an unbridged camera, unless I disable my entire firewall. Bridged mode works fine, since I'm able to allow traffic for the home bridge UI app in my firewall. Is there an equivalent way to do so for an unbridged camera?

I did search for this issue, and found #1461 , and a feature request #1485, but there doesn't seem to be any plan for a fix for this.

Is there any other way to make this work, except to disable my entire firewall?

### To Reproduce

1. Have homebridge-ring configured on a synology box (as a child bridge), running the homebridge app for synology
2. Configure synology firewall to block all traffic, and only add specific things to the allow list
3. Enable Unbridged mode, restart child bridge
4. Try to add the new unbridged camera in home.app

Things to note:
- DSM version on synology box: DSM 7.2.1-69057 Update 5
- DSM Homebridge app version: 3.1.2

### Expected behavior

I expected to be able to add the unbridged camera in home.app. The camera does appear, and I'm able to tap to add it, and it allows me to enter the setup code. However, it just spins for several minutes and ends with error saying the accessory is not reachable.

If I completely disable my synology firewall, then it allows me to add and stream the unbridged camera. I wasn't able to get it working by manually allowing the port the logs say it's using for the camera accessory either. Although, that wouldn't be a great option anyway, since the port changes each time the bridge restarts.
