[Solved] Broadcast from client on specific network?
-
Hi,
For simplicity, I have two networks, A & B. From network A I need to do a "directed broadcast" from a client on network A to B. What would I need to configure to allow this through pfSense?
As I have been unsuccessful so far, I suspect I need more than the pass rule I made with source network A and destination IP "b.b.b.255", as looking in the log it shows local broadcasts from that client, which is not what I need...
Thoughts, pointers much welcome. Thanks

@furom doesn't work that way. Broadcast is designed to be limited to its own network
, it should not pass L3 boundary..Be it directed, full or a multicast destination. The whole point of a "broadcast domain"

What exactly are you trying to accomplish that you think broadcasting from network A into network B would do?

@bingo600 maybe.. Just send the wol from pfsense, that has an interface in that network.
Maybe this would work for what he is trying to do.

Its a feature request for a udp broadcast relay.

I want to find a NAS using Synology's tool for that. I read this https://www.practicalnetworking.net/stand-alone/local-broadcast-vs-directed-broadcast/ and was mildly hopeful after that, but have not succeeded in making it work yet... Perhaps it will be easiest to just move it while setting it up, but was kinda hoping to find a way...

I have the same issue using the "remote app" on my ipad , for my Onkyo AMP.
I opted for joining the MMedia SSID (same vlan as Onkyo) , rather than infest my network with "Cross broadcasts".Now if embedded programmers would ..... At least give one a chance to enter a dest IP , instead of requiring to be on same L2

@furom finding your nas was never meant to work across networks. What is the exact discovery method they use, I have not been able to find any actual whitepaper or write up on this - other than udp discovery.
But what they clearly state on their help docs about not being able to find your nas - is that you make sure they are on the same network your trying to find it from.

Yes, I admit I was hoping I had missed something and this would be possible somehow, but get it. I will set it up, then move it. Thanks anyhow! :)

Why do you have to move it? what does its location have to do with what network/vlan its on? This why you use vlan capable switches ;) I can put any device that sits anywhere in my home on any network I want.
I just had to fix my cousins pc, thought she might have a virus - wasn't going to plug that into my normal network. So just set a port on my switch to be in my guest network and plugged it in there..

Logic move ;) And yes, it's awesome
