I have been using a MikroTik RB493G for some time, and I have the router configured with three VLANS. One VLAN covers the WAN (Eth1) port (DHCP), one covers Eth2-Eth5 (192.168.1.0), and one covers Eth6-Eth9 (192.168.1.128).
I recently purchased a MikroTik RB493AH to serve as a backup, and I would like to configure this router similarly. However, I cannot seem to figure out how to use VLANs to build two subnets.
I do know that the RB493AH has only one switch chip, which covers the 8+1 Ethernet ports. The RB493G has two chips, one that covers 4+1 and one that covers 4.
I thought that something like this would work:
config switch
option name switch0
option enable 1
option reset 1
option enable_vlan 1
config switch_vlan
option device switch0
option vlan 1
option ports "0 1 2 3 8t" # 8 is CPU.
config interface privlan
option ifname eth1.1
option type bridge
option proto static
option ipaddr 192.168.1.129
option netmask 255.255.255.128
However, this renders the router's Ethernet ports unusable by a computer.
When I study the documentation and the example RB493 configuration, it seems that I am missing something about how to assign an IP address to the two VLANs. I thought I understood the "implicit" notation (i.e., eth1.1).
Everything works when I reference eth1 (rather than eth1.1) in the "config interface" section. But this of course does not allow me to assign two different subnets to the to VLANs.
