Subnet discovery
-
Hello All, I am new to routing and am having an issue discovering devices across subnets.
For troubleshooting I can access the devices by ip, but I have a synology auto discover tool that will find my nas. It is not. I also have an hd homerun I'm trying to connect to plex, but it also does not find it.
So far I have added firewall rules for each interfact to allow any traffic from any source to any destination (just temporarily) to see if I can get it to find them.
This also does not work.What should I be working on next? (I am still learning)
Thank you!

@joejoe317 discovery isn't going to work across subnets/vlans.. Broadcast and Multicast is limited to the L2.. Now depending on the discovery method like mdns or ssdp, you could setup say the avahi or pimd packages..
Don't you know what your nas IP is? Set it up so you can use dns, mine is nas.home.arpa for example.
If you have to resort to discovery for something - just put your client on the same network your thing you want to discover is on.
