Hi,

USe "ifconfig" command. Example:

ifconfig xl0 10.10.10.10 netmask 255.255.0.0 broadcast 10.10.255.255

For default gateway you can use:

route add default 10.200.20.1

Make sure nothing set for default gateway first. Use "netstat" command to check your default gateway. Example:

netstat -rn

I already have a default gateway set, what is the easiest way to change that?

 

[dbase77]

Hi,

Remove the line by issuing:

route delete default

Then issue the command I gave you for adding default gateway.

Thanks, but I got an error saying
couldn't find device xl0

when I ran
ifconfig xl0 10.10.10.10 netmask 255.255.0.0 broadcast 10.10.255.255

got any tips?

Hi,

device xl0 is just for example. You need to put in your own device name. Run "ifconfig -a" or "dmesg" to find out your device name.

Thanks that worked, but once I rebooted it reverted back to the old IP, subnet and gateway.

How can I change it permenantly?

Hi,

Put these lines in file "/etc/rc.conf":

ifconfig_xl0="inet 10.200.10.33 netmask 255.255.0.0"
defaultrouter="10.200.20.1"

Make sure you use your own device name and ip address. It wont change when you reboot.
