I have 2 different IP ranges behind router. Router LAN is 192.168.20.xxx and few devices with 192.168.30.xxx address. In RUT240 it was easy just add alias in LAN settings page 4 fields to fill and it works. On RUTX09 it like gazillion fields to fill. Set up VLAN - tagged, untagged, then add LAN. I've done so many variations of these settings and none seem to work. I begin to doubt that is actually possible to achieve.... Please help.
