Hi folks, I have enabled Ip directed broadcast on one of our Routers, with appropriate helper address. If I enable "ip route-cache flow" on the interface and "show ip cache flow"; I get to see that the incoming interface is the interface on which I have enabled the broadcast ( with helper address) and the Out going Interface as "Null" with the destination IP Address as helper Address I specified. Where as for TCP Traffic Incoming and outgoing interfaces are seen proper. But the UDP Broadcast is getting forwarded to client machines.
Can anyone help me in understanding the basic of this.
