From what you wrote previously, it seems that you're not using the right commands to configure the bridge. After adding interfaces eth0 and eth1 to the bridge, you must stop referencing them. All the operations must be done on the br0 interface, including the request for a DHCP address (eg: dhclient/dhcpcd/whatever br0). Moreover, now the linux box can not act as Internet gateway anymore (unless it has some other connection to the Internet that you did not mention). You must use your ISP's upstream router as default gateway (on all the internal LAN boxes too). What interfaces was the win2003 server using previously for bridging and connecting to the Internet? -- [EMAIL PROTECTED] mailing list
