Good afternoon, I'm using RMerlin's 188.8.131.52.246.20 Merlin build software on my new RT-AC66U, and playing around with trying to get VLANs working. What I want to do is: WAN - Internet access, untagged LAN 1, 2, 3, wifi - VLAN A, bridged together (ala fairly normal) LAN 4 - VLAN B I'm wanting separate address pools on VLAN A and VLAN B, plus needing some specialized NAT configuration. I'm very familiar with Linux in general (so have no problems building the route rules, iptables configs, etc.) My problem is getting the Broadcom switch onboard to actually do the VLAN setup. I've been poking at the robocfg utility, however it seems to be just slightly incompatible with the newer BCM53125 chipset that's onboard the RT-AC66U - it doesn't quite do VLAN configuration correctly (it looks like the tagging method is getting changed from 802.1Q to something else) and can't even reset the stock settings correctly (comparing robocfg dump before and after - there's a few registers different in page 0x05 - and afterwards no traffic is flowing correctly across the LAN ports). I've looked through the init-broadcom.c source code as part of the firmware, and it is doing VLAN configuration with 'et robowr' calls and not using robocfg. I don't doubt I'll figure this out eventually with a combination of the source code to the driver and init-broadcom.c, but before I burn a lot of time to do so, I figured I'd ask if anyone here has gotten this to successfully work (either a newer version of robocfg, or some example scripts using 'et robowr' to do it)?
