| |
I have been unsuccessful in getting bridging to work with RedHat 6.0. I can see network traffic on both ethernet interfaces with tcpdump, and brcfg says bridging is enabled. My ethernet interfaces are in promiscuous mode, and 802.1 packets are being sent out from my box. But I cannot ping two machines separated by the bridge. I've read every HOWTO I can find, searched DejaNews and many archives for answers, but to no avail. I have attached my configuration below. Personal replies welcome.
