Greetings everybody,

    I need help configuring custom application that needs to be broadcasted over WiMAX network in OPNET. The application itself is simple : Ethernet server broadcasts request to all mobile nodes in the network and they respond back (shown on the Figure bellow). I have read how it is supposed to be configured, I know that the connection for broadcasting has to be UDP and i have tried to configure local broadcast to address 255.255.255.255 as well a directed broadcast but it did not work. I am using OPNET wireless 16.0 A.

Network topology:

Ethernet server -advanced model

Mobile stations- advanced model

Routers 
Base: stations -wimax_bs_ethernet4_slip4_router;

Backbone- router_slip64_dc;

Gateway- ethernet4_slip8_gtwy;

Links:

From ethernet server to gateway -100BaseT;

all other links are PPP_DS3;

I will appreciate any help.

Thank you!
