One or more of these connections may be over VLANs, and then you would have to use both vconfig and zebra. The vconfig and ifconfig commands you wrote in the original post look just right, the only other thing to keep in mind is that you'll need to enable routing, or forwarding as it is called in Linux. sysctl net.ipv4.ip_forward=1 or echo 1 > /proc/sys/net/ipv4/ip_forward I prefer the former. Modern distributions usually have /etc/sysctl.conf for sysctl settings too. > I dont know english too much, forgive me for the errors and > THANK YOU VERY MUCH BY HIS TO HELP US, > GRACIAS POR SU COLABORACION At least now I understand what you want to do. :) You could check out an old post of mine to see if you can use any ideas: http://marc.theaimsgroup.com/?m=105098558615614 Setup 1a looks like what you want, but if you want to use dhcpd as in the example, you'll have to run vconfig set_flag eth1.2 1 1 vconfig set_flag eth1.3 1 1 before starting dhcpd. Also note that the example uses the old sysctl setting.. On Fri, Feb 17, 2006 at 11:09:47AM +0000, Alex Zeffertt wrote: > > To create a vlan device on VID 10, > > 1.

Run "ifup eth0" If this doesn't work, try "ifup eth0.10" instead, but I'm not a Red Hat expert. //Peter
