@tyler_rm your links vs just posting the image here is a bit off putting for someone wanting to help.

Here is a post I did year a go or so on how to validate if avahi is working.

I personally am not a fan of breaking the L2 barrier like this - but in the link I go over how to actually validate if its working or not, etc. Hope that helps.

@sameerchouksey do you mean these 2 network segments directly connected to pfsense?

Or do you mean their are either upstream or downstream networks that get to pfsense via a transit network?
