Hi, I have a specific application that woks using local broadcasts both from server end and from client end...
The server is on Vlan 300 and users are on vlan 400.
I configured the following and then need to open specific ports - for testing purposes I am presently not using any ACLs - these will be implemented once it is actually working.
If I use the specific ports with ' ip forward-protocol udp (port number) - I can see traffic passing as I wish using Wireshark - packets pass both ways and are broadcasted on the destination VLAN as desired.
My only issue is that this application uses random ports and I would like to open all possible local UDP to pass between these two VLANs
I found the command ' ip forward-protocol any-local-broadcast' but my IOS does not support it -
So I also tried using
ip forward-protocol spanning-tree any-local-broadcast
