Wlan and local LAN on the same SubNetwork.

Hi, i have been gift with an RB532 Router, and I am very pleased with it. Although I don’t have a lot of knlwedge in networking, i managed to make it work, more or less.

My network is the following:

1 Cable modem 50Mbps->Eth1-RB532 ( this is the internet access).
In the LAN side, i have:
1 pc conected to eth3 ip: 192.168.5.x
3 pcs and a PS3 to Wlan on ip 192.168.2.x.
I made the rules for nat to “open” or trigger the ports i need and also i have been able to make a bridge between eth3 and wlan1.
In Nat there is a masquerade from all ports of the RB532 toeth1, so any port in the router has internet access.

The bad news are that Microsoft Windows Media Player Multimedia Server, is not thought to share files between two subnets, so i cant see multimedia server(the pc in eth3) from my ps3.

So i want to know if there is any kind of configuration in wich i can have same subnet in wlan and in ethx port. I have tried to give the same subnet address to both interfaces, but the result is that wlan does not serve dhcp, even in static mode, cant ping it. If i revert to two subnets situation, i can ping PS3, but i cant reach eth3 from ps3…

Any help?

Thanks in advance.


PS.- i have to say, that i tried to read everything i found on inet, including router os manual, wikis, examples, etc, but as thay are all codified in acronym terms, it makes it impossible for me to understand, becouse in each paragraph there are more or less 2-3 acronyms each 7 words.

You’re in luck as there is a simple solution to this;

  1. remove all IP address from the ether3 and wlan interfaces
  2. make sure your bridge has the ether3 and wlan ports as part of it
  3. create a new IP address for the bridge, say 192.168.5.1/24
  4. configure the DHCP to work on the bridge interface

The result will be all your local clients (PS3, WLAN, PC, whatever) will be on the same subnet and should all be able to see the streaming server.

Try this and let us know.

OK!!! i am going to home in two - three hours. As soon as i try it, i will tell. Thaks, Lots of thanks.
