Thanks for the replies. I do seem to have had some success with setting the server with: <br><br>address.host = ENET_HOST_ANY;<br><br>And then the client as address.host = ENET_HOST_BROADCAST;<br><br>Once connected it seems to work fine, but it does seem flaky to connect sometimes. I've also found that decreasing the timeout time for the client seems to have improved matter eg enet_host_service(sClient, &event, 100) (from like 5000).<br>
<br>Im happy with this, but Im not sure why it works, and I want to be sure that it will work on others routers/LANS etc (I've manged to test it on one router so far and it also worked there)<br><br>Any hints on how/why it works and if its reliable would be great! thanks again.<br>

Sorry if this is a basic question: I'm trying to setup a local game over<br>
wifi. So one client will create the 'server' and the other clients will try<br>
and join as clients. The problem is on a local LAN it seems they have to<br>
connect to the locally assigned IP of that server but I dont know how to get<br>
this through the code.<br>
<br>
I can get the client to connect to the server by manually finding the IP say<br>
192.168.4 but I need to get this through the code.<br>
<br>
Does this mean I have to get the server to do some kind of broadcasting?<br>
<br>
Thanks in advance!<br>

For a LAN session, the client broadcast a message ? is there any server out there ?, on a specific port.<br>
<br>
The server listens to this port, get the message and send a response ( as a broadcast usually so every client can see any changes in the server ) "Am I a server here, with my IP : XXX" ( and perhaps some other useful informations ).<br>
<br>
Now the client has received the response, so he can do whatever he wants...<br>
<br>
<br>
<br>
Hope it helps,<br>
<br>

The client-side needs to know either the ip address (whether local or external) of the server, or a hostname which resolves to the right ip address.<br>
You can use a free dns service, such as dyndns, to resolve to an ip address which you can change at any time without modifying the code. This would require you to have external internet access though, and wouldn't work on a local lan which isn't connected to the internet. Other than that, the only way to do it would be to have the user supply the ip address to connect to. All of the games I've played which support tcp/ip play use this method if they don't have a centralized server with a static ip that organizes all other servers.<br>

Yes this can be done easily with udp. Send a message to the ip 255.255.255.255 => the message will be sent to all hosts in the LAN. The server answers and now the client has the ip of the server.<br>
<br>
You could also use the IP 255.255.255.255 as serverip when you connect the ENet client, then it will search for the server itself and you want need udp.<br>
<br>
