I started this test with two separated interfaces. each one had its own ip address on different subnet. in this configuration I did NAT (eth1 used private subnet). using this configuration ping and all other worked fine. now I removed the IP address from the interfaces and gave on IP to the bridge. I (of cores) changed the subnet on the old private network to the one on eth0. I also cleared the arp cache but still nothing. I do have a strong feeling that I'm missing here something simple but I still can't place my finger on it :) ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
