Hello, this is my first post in this forum, so hello from Germany.
For the first part I'll talk about my network and my intentions for the Easybox which I can't setup.
I've been using the TL-WA850RE v1 with OpenWRT Chaos Calmer for years now, configuration was easy, it has one LAN Port and just b/g/n Wifi, nothing special.
The br-lan interface bridges the LAN Port with the Wireless Access Point. It is working as a Lan to Wlan "converter".
The Fritzbox DSL Router uses 192.168.1.1 and the OpenWRT has it's DHCP server turned off.
As I said, easy setup, no intentions for updating it because it's running fine.
Now I found my "old" Easybox 904xDSL
which has 4 LAN Ports, 1 WAN Port and b/g/n/a Wifi. (I don't need the WAN port and the modem)
I have to admit it looks very great on the display.
Getting OpenWRT to work on it was quite easy, but I don't know how to configure it. I tried setting it up like the TP Link above, but it isn't working.
My plan was to configure like this: in LAN port 1, there is a ethernet cable going in which brings internet access. The LAN ports 2-3 should be LAN "outputs" and for Wifi the same.
Maybe this is easier to understand: LAN1 -> LAN2 & 3 & 4 & Wifi
LAN1 should be configured as a DHCP client, it just needs to get an ip and internet access.
The Outputs (LAN 2 3 4 & Wifi) should be all in a subnet, for example 192.168.100.x with the Easybox as gateway at 192.168.100.1. I've been trying for 2 days, but I can't get it to work like I want.
Maybe you can help me
I don't know whether this is meant. Lan1 should be a DHCP Client which obtains an IP adress and routes the internet traffic into a subnet which contains Lan2,3,4 and Wifi.
Go to http://192.168.100.1/cgi-bin/luci/admin/network/switch (or whatever the Ip address of your device is), create a VLAN, and assign one of the LAN ports to it (you will need to first turn that port off in the first VLAN).
Then you go to interfaces and create a WAN interface, set it to DHCP client or static.
I don't know either. I am not familiar with your device. How many physical ports are actually there? Is there a dedicated WAN port?
Not that the text label on the casing don't always match the software port numbers. I see in your screenshot that the cable is plugged in a different port than the one you assigned as WAN.
The numbers are matching, i think switch1 is Right for me, Switch0 detects the lan cable plugged in into DSL as full duplex so this should be the modem which I don’t need.
I think it could be easier to see the whole picture if you send the output of the following commands? Please use Pre-Formatted text tool </> to include the code, and remember to redact your MAC addresses and any passwords.
But I tried to set up eth0.55 (DSL/WAN Port) as dhcp client and with the black LAN cable coming from the Fritzbox plugged in into DSL it's getting an ip adress. The OpenWRT can even ping 1.1.1.1, but no dns and the computer also has no internet access.
I set the config for the DSL 100mbit Port to static and put in dns servers, now openwrt can resolve URL’s and opkg can update. But still no internet for the clients.
If I were you and I don't need too many LAN ports, I'd aim at ignoring the XRX200 Switch altogether and just doing with the other switch like what you were trying to do in the beginning (well, unless the two switch work on different CPU cores).
Now you have to decide if you want that router to have it's own subnet (in which case the VLAN scenario is the way to go), or if you wnat it just to function as an access point within the main subnet, in which case you could just start from the default 1-VLAN configuration and connect the upstream cable to a port in the RTL switch.
Yes it would be fine with 1 LAN as input and 3 LAN Ports as gigabit outputs.
The problem is now: the dsl port gets an ip assigned without problems, but this is not working with a lan port. The lan port just doesn’t get an ip assigned , i don’t know why.
And the second is, the client has no internet access.
Because I'm a new user, I can't make a new answer for 22 hours from now....
But when the Lan cable coming from the Fritzbox is plugged in into DSLWAN it obtains an ip, but when plugged in into LAN1 I can't obtain an ip.
Here is why, I think. The gateway should be the IP of the upstream router.
Edit: or you could just make that interface as DHCP client. If you insist on having an IP of your choice, you can set it as static lease on the upstream router.
While the Easybox 904 xDSL is quite amazing hardware, it's also very, very special and not quite beginner friendly (at all). Especially the switch/ VLAN setup is very special, as your device has two internal switches, with the wireless cards (which are a nightmare of their own) internally bridged via a special VLAN tag.
For the details you'll have to read the long archived thread imported from the old forum, but this device is very different from just about anything else running OpenWrt. If you're looking for a painless device, there'd be much, much easier (and more reliable) alternatives.
