Archer VR2800 (ac2800) and Zyxel 4g outdoor router - connection issues
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I use the TP-link VR2800 as my main DSL router.
as my broadband is intermittent, I have bought a Zyxel LTE7480 outdoor router/antenna and want to connect this to the TP-LINK.
I want to keep the TP-Link as my main router and have therefor DHCP activated there and have switched it off on the Zyxel.
I have given the xyzel a fixed IP of 192.168.1.10 and switched on ip-passthrough (seems to be the equivalent of bridge mode in order to avoid a double nat issue when it is on router mode?)
Not sure what to do at the TP-Link side
no matter if i leave it in mode 1 (DSL router mode) or mode 2 Wifi router mode) or when I connect the zyxel to the WAN or LAN port on the TP-Link, i cannot get this to work.
Would anyone be willing to give my advice to get this going?
What I wnat is to be able to plug in my DSLwhen it works but have my zyxel as a back up. Even better would be if both could be connected and perhaps the DSL connection bound to a single lan port out. (as I have seperate guest accomodation which would then be served by that).
I have now tried almost everything but have to stop fiddeling each time my guests are back or when my wife goes online for work...
I did get the 4g router working through the tp-link a few times but for some odd reason not everything worked correctly over wifi (but ethernet connection -seemed to -orked ok)
summary of setup:
TP-link VR2800 in house connected to BT DSL
a couple of RE650 around the house to extend (shame no mesh)
Also a switch connected to ethernet sockets around the house.
In the guest accomodation I have an Archer C58 with a guest Wifi ssid setup.with a LAN cable connecting the wto archers via LAN ports
Hope some one can help, after hours of youtube and google, I am at a loss.
many thanks!

The idea here is with IP Passthrough configured to transfer the public IP address from Zyxel device to your VR2800 LAN4/WAN port (VR2800 in WIreless Router Mode).
That means VR2800 LAN4/WAN port configuration should be Dynamic IP so the VR2800 can receive the public IP address from the Zyxel.
According to your Zyxel user guide - Chapter 6.10:
https://download.zyxel.com/LTE7480-M804/user_guide/LTE7480-M804_1.00.pdf
On Zyxel I would suggest to use IP Passthrough mode - Dynamic and connect the VR 2800 LAN4/WAN port to the Zyxel ethernet port.
Zyxel LAN IP address could be 192.168.1.1 (for example)
Zyxel DHCP server could be 192.168.1.100 - 192.168.1.199 (for example)
These won't matter when the IP Passthrough is activated - that's what I am understading when reading Zyxel's user guide.
VR2800 IP address could be 192.168.1.1 (for example)
VR2800 DHCP server could be 192.168.1.100-192.168.1.199 (for example).
You may need to rebooot both devices when IP Passtrough is activated so the setting would take effect.
Try to test this scenario, cause otherwise without IP Passthrough activated, a double NAT would be introduced in your LAN.
Also you can do some research or ask in the Zyxel community for an additional guidance.
As I understand a tough place to bring an Internet connectivity.
I forgot to suggest that you could make a device current configuration backup, once when in DSL Modem Router Mode and once when in Wireless Router Mode.
Thus when you switch between two modes you can easily get back your current VR2800 configuration:.
What was the VR2800 WAN port IP address when you've activated the Zyxel IP Passthrough feature, was it your public IP address or not ?
Zyxel should be connected exactly in LAN4/WAN port, when VR2800 is in Wireless Router Mode, to be able to pass its public IP address to the VR2800 LAN4/WAN port.
In this case you can use only LAN1-LAN3 for cable connections and VR2800 Wi-Fi for wireless.
You can test also leaving the IP Passthrough disabled if former doesn't work.
That way the VR2800 LAN4/WAN port will receive a Private IP address - you'll have a double NAT in your network, but you still will have an Internet connectivity.
Unfortunately I can't be much of a help with the Zyxel device, except interpreting its user guide.
As I pointed earlier, you have to search for help in the Zyxel's community forum.
