Automatic updates when cascading routers (LAN to LAN)

Hello everyone

I’m not an expert on networking. Here’s my current setup:

I have two routers, one of which serves as a network box for Google Fiber. I have an ethernet cable running from the first router’s LAN port to LAN0 on the Turris Omnia. I have disabled DHCP on the Omnia and assigned a static IP.

I’m trying to do an auto update but the updater is not finding an internet connection because it currently expects it to be coming via the WAN port. I tried bridging the WAN interface with LAN (eth1). WAN is currently set to DHCP.

Here are some screenshots:
Physical Settings for WAN:

I would appreciate if someone could point me in the right direction here.

Thanks.

Why aren’t you using the WAN port? Any specific reason? I have a similar box from my ISP and I just cascaded the router plugging the WAN port and connecting it to the ISP device.

If I use the WAN port, I ended up having issues with devices on the secondary router accessing devices connected to the primary router and vice versa since I had to give the router a static IP outside of the primary router’s DHCP range in order to still access and configure it.

I am using the Turris to extend the range of my network so I would prefer the ability to seamlessly access all devices on the network. Is there a way to do this while still using the WAN port?

Theoretically i THINK there might be a way, but i am not sure if it might be possible. To give the Omnia a “gateway”. OR another solution use 2 cables. 1 to use as WAN and 1 to use as network :slight_smile: Both connected to your primary router.

He can use his Omnia as a switch, but it will send data collection (if he wants it), but it won’t say data from honeypot (because it’s not primary/first device on the internet)

That is the issue. Normally i would agree with you. But auto-updater searches for “WAN-zone”, which off course in situation with Omnia setting up as a switch will not work.

So to be able to use auto-updater and as well to be able to contact devices which are connected to the Omnia, use…two cables.

Cable 1 - for auto-updater: Omina (WAN) --> Primary router
Cable 2 - for devices to connect to other devices: Omnia (LAN) --> Primary router.

Thanks for the answers. I’ll try that setup.

@geo_lee, Use that solution for now, but i THINK that there MUST be a solution with just 1 cable ON the WAN. I’ll let you know if i stumbled upon something.

EDIT2: What about (LuCi) Network --> Firewall

Everything FROM WAN to LAN is being rejected. (Firewall). So logically speaking, if you disable this or just accept everything…then i guess things should workout the way they should right? You have not forwarded anything from your Primary router to your Omnia, so would that be oke?

If anybody knows what i do not please do correct me.

I’ll give the firewall setting a try too when I get home. Thanks.

Hmm…the two cable solution seems to cause me to lose access to the Turris Omnia once I plug into the WAN port.

I tried the Firewall solution… is this right? It doesn’t seem to work either.

@geo_lee, i MIGHT have found another solution with only 1 cable.

Relay bridge. I am not sure of it, but in theory it might kind of work.

When you on your LuCi–>Network–>Interfaces—>WAN (edit)–>Click on “Protocol” in the “general setup”. All the way down you see “Relay bridge”. Can you experiment with this a bit?

BTW: Don have LAN in your WAN zone(Purple). You have LAN in your WAN zone.

In your WAN zone should ONLY be having “wanX” in there.
