Hi all. I´m wondering what would be necessary to build a wireless network repeater. This means that pakets received on a wireless network interface get resent over the same interface. How could I prevent that pakets start looping around in the network when more than one repeater is used? Think of the following situation: C ----- R1 ----- R2 ----- BS C = Customer R1, R2 = Repeater BS = Basestation If BS would send a paket to R2, R2 would resend it over the same interface. R1 hears this paket and repeats it, so it can be received by C. But not only C receives it, R2 also does. It repeats the paket again, so it´s like playing ping-pong with network pakets. Any idea how to avoid such problems? The used protocol is IP, there will be a vtun-connection established between C and BS, R1 and R2 only act as ip routers (and as repeaters). The first idea I had was to use a tap device on R1 and R2 to listen to the pakets and to filter pakets that have been recently sent. But what would be the impact on the performance with this solution? The routers are equipped with a Cyrix MediaGX 233MHz cpu, the wlan interfaces have about 6-7 MBit/s bandwith for the user (actually, Lucent WaveLAN/ORiNOCO). How could this filtering be done? Any help appreciated. tia. Bye, Mike - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.rutgers.edu
