Having a hell of a time trying to get VLANs working on a Rev. I Actiontec router. I previously had a Rev E in this location that was working just fine.
My goal is to have 3 VLANs, two tagged ports, and three untagged ports:
Port 1 -> Tagged 1, 2, 3
Port 2 -> Tagged 1, 2, 3
Port 3, 4, WAN -> Untagged (PVID) 3
It seems to come down to an issue with the untagged ports. Take Port 3 for example: frames coming into the port get properly tagged for VLAN3 and I can see them on Port 1/Port 2. However, the return frames from Port 1/Port 2 either do not get untagged when sent out to Port 3 or never make it to Port 3 at all. So my device on Port 3 (which is not VLAN aware) can't process the responses.
This seems to line up with the last few posts of this old thread:
http://www.dslreports.com/forum/r29130839-VLAN-configuration-on-MI424WR-Gen-3-Rev-I
Consensus seemed to be that the new switch used in the Rev I does not properly untagging frames on ports set with a PVID. The interesting part is that a non-VLAN device plugged into the WAN port works fine. I can exchange frames/packets between my Port 1 device and WAN device over VLAN3 without a problem. Internally, the WAN connection is presented as a separate interface (eth1), but I can't tell if that is part of the MV88E60 switch or a separate controller.
Further complicating the issue: non-VLAN devices on Ports 3 and 4 can communicate but they cannot communicate with the WAN port, even though they are supposed to be all on the same VLAN.
Anyway, has anybody successfully gotten VLANs to work with non-VLAN aware devices on the Rev I? Is it a software problem? Hardware?
