Hi Guys,
I'm trying to get my TP-Link 1043ND to split the incoming Huawei signal for PPPOE and VOIP. I'm not sure if my idea will work so I would welcome any suggestions.

Huawei -> TP-Link -> Thomson

I'm running openwrt, and have tried to configure the VLAN on TP-Link to redirect the Huawei connection. So far, I've managed to get the TP-Link to work and obtain a PPPOE connection. This means the network devices in my house are now able to use the FTTH via the Tp-Link (bypassing the Thomson).

The problem I'm getting is that I can't seem to get the TP-Link to pass the 821/822 VLAN over to the Thomson. The Thomson doesn't seem to get a VOIP SIP link up. Looking at the event logs, it seems that the management port is up.

I have this in my /etc/config/network file (a truncated output):

config 'switch_vlan'
option 'device' 'rtl8366rb'
option 'vlan' '1'
option 'ports' '3 4 5t'

config 'switch_vlan'
option 'device' 'rtl8366rb'
option 'vlan' '621'
option 'ports' '0t 1t 5t'

config 'switch_vlan'
option 'device' 'rtl8366rb'
option 'vlan' '821'
option 'ports' '1t 2t'

config 'switch_vlan'
option 'device' 'rtl8366rb'
option 'vlan' '822'
option 'ports' '1t 2t'

Note that my TP-Link's WAN port is busted so I'm using the switch ports for the incoming routing. I have the Huawei plugged into port 1, and the Thomson plugged into port 2. (Port 0 is the WAN port that is busted). Anyone have ideas on what else needs to be changed? Thanks in advance

So just want to update you all that another confirmed TP link TLWR1043 user here who has gotten it working with openwrt

For the longest time i was stuck trying to figure out what was wrong with my openwrt config. But thanks to jssc who confirmed that it can work, I persevered.

The issue in my case was somehow the Telephony configuration in the Thomson was messed up. I ended up deleting it and adding it back again and it now works. Previously, the "Registered" field showed an X.

Just FYI, settings for Telephony on Thomson is:
SIP URI: <your Maxis VOIP number, e.g 03xxxxxxx>
username: <your Maxis VOIP number, e.g 03xxxxxxx>
password: <your Maxis VOIP number, e.g 03xxxxxxx1> (notice the extra 1 digit)

Thanks for your info. Maybe I didn't make it clear, but I managed to get it working That was after a long period of troubleshooting

I originally thought that there was something wrong with the VLAN settings that i had on the TP-Link WR1043 (openwrt). Turns out the settings were fine. It was the VOIP settings in the Thomson router. So this is just to let you all know, in case your VOIP doesn't work on the 821 VLAN, that maybe it is due to some glitch on the Thomson router. I discovered this when I accidentally 'flush'-ed the VOIP profile from the Thomson router after logging into the telnet terminal. After I created a new one from scratch, the VOIP started working properly.

Thanks for pointing that out for me. Sorry I got confused by what you meant

My WAN port is actually physically dead.. probably due to line noise from lightning It was working before.

It's good to know about the potential problem with the WAN port due to the firmware on the newer 1043 models; so I will bookmark it.

For all of you out there, imho the TP-Link WR-1043ND quite a good value for a nearly full featured router @ <RM160, USB port, Gigabit ports, 8MB flash for openwrt. Only thing missing is dual-band N wifi.

However, if there are other good value routers out there, I would like to be proven wrong (for my future purchases)

I received the above PM, so I am just putting my response in public for the benefit of all:

Yes, you are right.

My custom router is the TP-Link WR-1043ND running a custom firmware, openwrt. I configured openwrt to have VLAN id 822 go from WAN to a specific LAN port. You may find some more instructions in this thread.

After that, just plug in the thomson router to the specific LAN port above, not just any port. It should work with no changes to the thomson router itself. If it doesn't, like in my case, you may have to delete the telephony settings and re-add it back.

1) connect the dedicated VLAN port of your custom router to the Thomson WAN port
2) it shouldn't matter if the two routers are on the same subnet or not. If your mikrotik is sending VLAN 822 data to the thomson, it would be in ethernet frames, which have no bearing on the higher-level IP protocol, I believe.

and 3), you shouldn't need to do anything to the thomson, other than disabling the wifi. unless you want to have two wifi hotspots.
