Kalcifer OP , 5 months ago to homelab in [WORKAROUND] Nextcloud portforward stops working when it is moved to a bridged network

That’s… interesting. Router B shouldn’t be involved at all with this, it should be blindly forwarding the packets. That’s a layer 3 error!

Indeed! I’m quite stumped.

How’s the bridge set up?

I set it up using this guide.

Have you made sure router B doesn’t do DHCP […]?

Yup, it’s disabled.

Have you made sure router B […] doesn’t take the IP of router A by accident?

Yep, it’s set to be static.

Kalcifer OP , 5 months ago to homelab in Does Avahi work over a bridged network?

I’m not familiar with how Avahi works, but I assume it uses broadcast packets.

It does, yeah; multicast DNS uses multicast packets e.g. 224.0.0.251 (ipv4).

Do you actually have routing between two networks, or is it just a wireless bridge?

It’s just a wireless bridge.

Do broadcast packets transit the bridge?

They do.

Kalcifer OP , 5 months ago to homelab in Does Avahi work over a bridged network?

Router B is bridging Device B to Router A’s network, so they aren’t on separate vlans; thus, it shouldn’t require an mDNS reflector as that repeats mDNS between separate subnets.

Kalcifer OP , 5 months ago to homelab in Does Avahi work over a bridged network?

Router A would also need to bridge in order for that to work

Why would Router A also need to be a bridge? Router B is configured to bridge its devices to Router A’s network, so, from what I understand, its devices are treated as if they are on Router A’s network – bridging is layer 2, and mDNS is layer 3 (afaik), so Avahi should be able to resolve across the bridge.

On the other hand, there are ways of setting up Multicast Forwarding if the router supports it, or you could have a device in both networks that does Avahi/mDNS Reflection.

Wouldn’t this only matter if Device A, and Device B were on two separate vlan’s?

Are your clients all on the same subnet

Router A (192.168.0.1) is a different subnet than router B (192.168.2.1).

Make sure you’re actually doing a bridge

Bridge was added using the linked guide (it uses relayd).

Kalcifer OP , 5 months ago to homelab in What's the proper way to create a wireless bridge between two wireless routers?

Yea Qualcomm is hit or miss (with more misses than hits) but never Broadcom, they never release drivers for their stuff without NDAs and lots of fees n shit (Fuckin assholes man lol). In fact you should avoid anything Broadcom, they recently acquired VMware and before the ink had even dried they announced they were revoking perpetual licenses to make people/business move to a subscription model.

Noted!

But back on topic, WDS is a more full featured version where both the primary router and secondary ones are configured to bridge with each other. Kind of like a proto-mesh.

Gotcha. From what I’ve read, it appears that the AX73 doesn’t support WDS, which I thought was weird since its a pretty new router.

It’s been a long time since I’ve used this mode, but from what I remember, it’s under the AP mode setting (Where you would select AP or Router mode) you would select Repeater mode then configure the SSID name and Security settings exactly as the primary router. Sometimes there was a dedicated spot for this, sometimes you just set it on the normal SSID Security settings screen

I found this guide for creating a wireless bridge. It doesn’t feel as elegant a solution as simply hopping onto Router A with Router B, but it at least functions.

Aside from the fact that hte AX73 isn’t supported by OpenWRT, what steps would you suggest if one were to flash OpenWRT to accomplish this?

Kalcifer OP , 6 months ago to homelab in What's the proper way to create a wireless bridge between two wireless routers?

The tp-link Archer AX73 doesn’t support OpenWRT, but the second router (tp-link Archer C7) does, and has it installed.

Kalcifer OP , 6 months ago to homelab in What's the proper way to create a wireless bridge between two wireless routers?

see if your router can support OpenWRT

I have an Archer C7, to which I have already flashed OpenWRT.

avoid any routers with Broadcom or Qualcomm

Noted! I assume that the Archer C7 is an exception to that? It has a Qualcomm chip afaik. But, yeah, the AX73 is Broadcom.

Use the AX73 as your primary and the OpenWRT one as the repeater node and you’re set.

Is that not what WDS, or 802.11s is (I’m not arguing, I am simply unaware, and I would appreciate correction!)? I’ve tried setting this up a number of ways – all to no avail. I haven’t been able to identify exactly where the problem lies in the setup, as I am not knowledgeable enough about network administration yet. The Archer C7 is able to connect to the AX73 just fine, but any device connected to the Archer C7 is unable to reach the AX73. Would you be able to provide me with any instructions, or recommendations for guides to set up what you are describing? I’m missing some important set up step, or I’m improperly configuring something.

If Ethernet between the 2 is viable, go with that instead

I would like to try and set it up over a wireless link.

Kalcifer OP , 6 months ago (edited 6 months ago) to homelab in When is it necessary to have SSL on the LAN side of a reverse proxy (between the reverse proxy and the server)?

Only if that traffic is using broadcasts. Wired networking on moden hardware is strictly point-to-point, PC1 is completely unaware of any traffic between PC2 and your home server or whatever.

TIL of PPPoE! Could this still be circumvented through ARP spoofing, though?

Kalcifer OP , 6 months ago to homelab in I'm looking for recommendations for a cheap, and basic OpenWRT router

What model?
