Hello,
IP alias is not implemented on RUTOS 7 yet. But you can specify it via CLI/SSH client. You should connect to the device via the CLI/SSH client and make a small fix. Modify the vi /etc/config/network (press “i” to start edit) file by adding alias entry at the end. It should look like this:
config alias
option netmask '255.255.255.0'
option proto 'static'
option interface 'lan'
option ipaddr '192.168.1.10'
Save changes (Esc and :wq). Restart network interface: /etc/init.d/network restart
Regards.
