I want to use one of my eth card as a gate , could any one tell me how to set it up.
rl0:1
rl0:2 seems not a valid device name, where can i find a legal name for it, or how to create one.

thanks

january, please do not hijack other posters' threads with your own questions. Start your own thread in the appropriate forum.

OK, now what BSD are you using, and what is the output of
$ ifconfig -a

?

Sorry, sincerely! I don't meant to disturb the forum.

the out put was as following,

I've tried aix on IBM, it troubles me with the same question.
perviously , i did the same thing on slackware, redhat , mandrake
it can be configured with
ifconfig eth1:1.......
but on freeBSD or AIX I can not find the way
can you tell me what part should i study.
Thanks!

Your network cards are xl0 and rl0. UNIX uses the driver name to enumerate interfaces, unlike Windows and Linux which just use generic interface names. On a UNIX or BSD based system network cards are numbered like this:

driverX0
driverX1
driverS0
driverA0
etc...

Also, UNIX systems don't use interfaceN:N to describe aliases (that notation actually indicates VLAN, on some BSDs).

Could you show me how to create that alias
for dual IP on one eth card ( for freeBSD )?

Thanks

Have you tried reading the man page for ifconfig(8), by any chance? It should be pretty obvious if you have. It's exactly the same as normal ifconfig, only you add "alias" to the end. If you want to do this automatically at boot time, you can add the full ifconfig command for the alias into /etc/rc.local. That method is now deprecated (but it's the easiest). Check the rc(8) man page for more options.

Yes , I did look the man about ifconfig but tried in vain

ifconfig rl0 xxx.xx.xxx.xx mask.mask.mask.mask alias
ifconfig: ioctl (SIOCAIFADDR): File exists ???????????

I also tried put some line in rc.conf
ifconfig_rl0_alias0="xxx.xx.xx.xx netmask mask.mask.mask.mask media 10baseT/UTP"

what's wrong with my command ?
Thanks

Are you trying to assign the same IP to two NICs, or assign it twice to the same NIC?

I have two ethernet card and
want to assign two different group of IP to the same ETH card ( rl0 )

for ex.

freeBSD xl0 ---- 1.2.3.45
rl0 ---- 10.9.10.250
|
|
---- 10.9.20.250

Thanks

perform the following steps then it seems work.

1>new file as following
cat /etc/hostname.rl0
inet 192.168.200.1 255.255.255.0
inet alias 192.168.210.1 255.255.255.0

2>
ifconfig rl0 inet alias 192.168.210.1 netmask 255.255.255.0

restart again and it works
