Hi, i am a student who currently doing my last subject called " Final year project" in my universitiy. I am facing 1 problem now which made me cant proceed to next step of my project. My project title is "Investigating Quality of service (QOS) Requirements for Online Game Applications over IP Switched Network". The experiment pad for this project have 3 pc and 2 router with some other software
The problem i facing is "when Pc1 host a warcraft 3 game, Pc2 cant see any host game from the list in LAN network when they are connected".
The network topology is like that:
Pc1 - [interface 1] Cisco Router [interface 2] - Pc2
IP address:
Pc1 - 192.168.0.18
Interface 1 - 192.168.0.17
Interface 2 - 192.168.2.2
Pc2 - 192.168.2.3
Pc1 can ping to Pc2, so they are connected.
So i keep on doing some accesslist command and other to test whether PC2 can see any game from the LAN list, but cant. End up I open a software call "Wireshark" to see the flow packet for both PC. And i found out something, When PC1 has host/create the game, the wireshark constantly show some udp broadcast packet.
Source: 192.168.0.18 ; Destination: 255.255.255.255 ; protocol : UDP ; source port : 6112 ; destination port : 6112
PC1 keep constantly sending but PC2 cant receive any, and i know the router default blocking any broadcast packet to forward. When i plug them to a cisco switch, PC2 can receive the broadcast packet from PC1.
So my current goal is to let my router forward the broadcast packet to PC2, but i even have try some commandline like
ip forward-protocol udp 6112
ip helper-address
ip directed-broadcast
and others....
and PC2 still cant receive any broadcast packet from PC1.
Is anyone know how to help me solve this situation?

cobo
