Long time lurker, mainly because the time I started actively using OpenWRT coincided with profound changes in the way I live. Now I'm going full-OpenWRT. I already have a Linksys WRT1200ac with OpenWRT, and looking into adding a Banana Pi R3/R64. Wanted to ask for some advice/guidance to plan ahead though. I did search old topics, but have yet to find anything like my question.
I have an ADSL modem with 4 LAN ports and a DSL port, currently acting as the main gateway. It does support VLANs, but doesn't have enough configuration possibilities especially with respect to IPv6. I want to manage my home LAN through OpenWRT. However, there are multiple devices near the modem, so I also want to keep using its LAN ports and avoid adding yet another network device.
The plan is:
- Modem Port 1 to OpenWRT Router WAN, with VLAN0. Not other devices in this VLAN.
- Modem Port 2 to OpenWRT Router LAN, with VLAN1. All devices at home will live in this VLAN.
- Modem Ports 3 and 4 connect to the TV and any other devices (via a dumb 100Mbps switch or something). This VLAN is controlled by the OpenWRT router, DHCP and all. So essentially the ports 2 through 4 will work as a switch for OpenWRT LAN side.
Do you think this would work? I did draw something to better explain but I'm so new to the forums that I haven't found how to add images yet. Thanks in advance for the ideas!
