In Home Web GUI Being Blocked/Unreachable

[AZDNice]

Hello, I am trying to reach a In-home address/Web GUI but I keep getting the below errors. The only changes I have made on my Asus RT-AC3200 running Asuswrt-Merlin was Install AB-Solutions, Entware, Pixelserv-tls, and Skynet. I can see it on my Client Status listing however if I try to ping or reach it via the web GUI I get the errors below. Any assistance in this matter is appreciated. Thanks in advance for your time and help!

Where is this in-home web GUI hosted?

 

[AZDNice]

@kfp Local here. Actually it's an in home server. that I normally type in the net address in the address bar of google or firefox. Hope that answered your question.

These traffic are switched so shouldn’t matter what scripts you install or ad-blockers you have.

Though, there have been several users that reported problems for traffic between wifi and wired clients..is this your case as well?

@kfp you are correct. It is on a wireless network trying to be reached by a wired client.

@kfp From windows cmd when I ping...4 packets sent and 4 packets received, but it also said unreachable..??

@daviworld would you happen to have an Idea?

Oh, I actually didn't look at your screencap too closely until now, what ping is telling you is that there is currently no route to that host.
I'm assuming the Windows machine is on wifi and the server you're trying to reach is wired?
Can you double check the IP of your Windows machine and make sure it's on the same subnet?
Do you also have guest Wifi enabled? Might want to double check your Windows machine is not accidentally connected to that?

Anytime you ping something, and get unreachable back. It indicates a routing/connectivity issue. You mentioned trying to reach a local IP, but how are you trying to reach it?

Openvpn, static route's, multiple SSIDs, remote, etc

@kfp it is actually the other way around. wired windows machine trying to connect to web gui of a wireless server. However, i can see them both on my client list in Asus GUI

Hello @daviworld , Through google web page just like the asus router gui

@kfp Can you double check the IP of your Windows machine and make sure it's on the same subnet? :Yes same subnet
Do you also have guest Wifi enabled? Might want to double check your Windows machine is not accidentally connected to that? No, Guest is not enable. And this PC is wired on the same network.

 

[kfp]

Can you paste the contents of the routing table on the PC?

If on Windows type ‘route print’ into command prompt, if on Linux any of these would work.

[daviworld]

Based off your routing table I only see your network, loopback, and multicasting. Also, since the default subnet allows up to 254 host and I don't see another network. I can only assume maybe we are missing a network or a public route.

So far I was testing using a subnet of 192.168.1.0, but couldn't reproduce the issue on my router

Can you try pinging the server device from web GUI of the router? It’s under Network Tools.

That’s way too slow for a wired device, but anyways, what’s happening is before your Windows PC ping, it’ll do an ARP request and I think that’s whats failing (there has been a lot of reports of flakey broadcast between different interfaces).

@kfp if I connect wired, now I can see it and connect to it through web gui from another wired client. But I prefer to have the server wireless

Ah, so basically you’re seeing what some were experiencing (wifi to ethernet weirdness with broadcast traffic).

Try turning off the usual suspects in Professional settings under Wireless for each radio: Smart Connect, Roam Assist, Airtime Fairness
