I have an interesting dilemma. One of my colleagues wrote a script to have a control system listen for activity on UDP Port 4999 for broadcast traffic (192.168.99.255) from devices (audio/video streaming). On a consumer WiFi router (Apple Airport Extreme) this tests works great, issue is we replaced all the consumer products with a Cisco 2911, 2504, and 3702 WAP.
Currently in a VLAN using a class C network, the same testing units fail. What could be preventing him from being successful in this Cisco scenario versus the Apple consumer WiFi Router?
The Router is running 15.4(3) M1 (2911-A-K9). I know you can't ping ports because of the differences between the layer Protocols, but I am at a loss to explain why he can't do what he expects based on his Consumer router experience.
Would the command in Global Config help: " ip forward-protocol UDP 4999 " ? Any ideas?
