Thanks again, Jan. see my explaination in details below. >===== Original Message From Jan Kiszka <[EMAIL PROTECTED]> =====

I would probably need run UDP/IP over RT interface for my testing. Can I use the rtifconfig to bring rteth0 up first without assigning IP. and then configure a linux network interface (proxy) and run dhcp to get an dynamic IP address for both the RT interface and linux interface?

In this case, if I assign a ip to RTeth0 via rtifconfig, and then i configure this same ip on linux eth0 interface, 1. will the UDP/IP in RTnet works (RTping the internet, sending UDP via RT eth0 to internet for example) ?? 2. Will the TCP in the linux work (tcp connection with the internet machine, for example) Really appreciated.
