UDP Helper Configuration Example

Cross-Network Computer Search Through UDP Helper

Network requirements
PC A resides on network segment 192.168.1.0/24 and PC B on 192.168.10.0/24; they are connected
through Switch A and are routable to each other. It is required to configure UDP Helper on the switch, so
that PC A can find PC B through computer search. (Broadcasts with UDP port 137 are used for
searching.)
