I would appreciate any info to some resources. For example a technical document covering this issue or similar. My setup is a kernel 2.4.31 with bridge-utils 1.0.4. The box have three network interfaces eth[0-2]. Bridged interfaces are eth[1-2] (router,dmz), eth0 is my intranet. I use DLINK network cards with sk98lin driver. Many thanks in advance.
