Can't connect to the internet
I had some problems with internet in the past few months and I reported the issue to my ISP.
Today they sent somebody to see what's the problem, but I was at work when guy arrived.
When I came back home I saw that he replaced the router.
Router is ZXHN H267N V1.0 V1.0

So I turn on my PC and then I realized that it has no internet access.
Through further investigation, I realized that devices connected to WLAN and LAN1 have internet access, but devices connected to LAN2, LAN3 and LAN4 don't have internet.

I remembered that I have to enable them in router settings, so I did that.

But it still doesn't work.

I have 2 devices that need to be connected to LAN.
My PC and Raspberry Pi.
They both have internet when I connect them to LAN1.
But when I connect them to LAN2, 3 or 4, they don't have internet.

Devices connected to LAN2, 3, and 4 can access stuff from local network, but can't access rest of the internet.

Windows Network Troubleshooting says this
https://steamcommunity.com/sharedfiles/filedetails/?id=1872738342


On the old router, both Pi and PC worked at the same time. But on this router, only device connected to LAN1 works.


Can somebody please help me fix this?
I'm tired AF, but I won't be able to fall asleep until I sort this out.

Yeah you are literally locked out of everything. You won't be able to port forward without full admin level access.

Well, I was going to say why not try it with the mode it's in now. Was there errors? wasn't working right?. I didn't catch most of the recent thread so not sure exactly why you changed it and what it was before.

Can you try running that shield's up test again and see if it sees any open ports?.
It doesn't see any open ports.
It's trying to detect open ports on my public IP 109.175.104.139
But ASUS WAN IP is now 192.168.1.5
And while ZTE was in bridge mode, ASUS WAN IP was 100.82.30.242

I think that WAN IP and Public IP should be the same.

What I think is going on is that ZTE's WAN IP is same as my Public IP.
But ZTE gives a random WAN IP that is not connected in any way to the rest of the internet to ASUS router

ok, how about this. What port number is it that you want to un block and is this service already running and accepting connections?. If so is it on your computer?. What program?. Have you ran netstat and can confirm the port is listening?.

He is running as a limited access user account on the router. He needs ROOT / ADMIN level to change any of the advanced settings. His ISP clearly has given him a limited access account. They probably don't want him port forwarding.

the router or the modem?. As far as I know his router should only have an admin account and nothing else.

Nope I've come across several routers that are locked down in my time. Sometimes the ISPs will use a combination of the admin@serialnumber and part of the MAC address to make the password or use the last 8 digits for the admin password
combined with the serial number like this:

Account: admin@serialnumber
password: @serialnumber first 8 digits.

Do you know what model router he has?.

This is from where I can access my router via its WAN IP

:pressX:Internet :hintarrow: :pressX:ZTE :hintarrow: :correct:ASUS (LAN and WiFi) :hintarrow: :correct:Raspberry Pi's WiFi hotspot (Raspberry is connected to ASUS via LAN cable)

Bare in mind that some ISPs doesn't allow to route direct request to your assigned public IP. This means that you won't be able to get connections to any port you have open on your machine/router WAN interface unless you're in the same network of your ISP.

I had that problem with my ISP and I had to switch to another plan in order have a "real" public ip. Of course, commercial staff never understood my requirements when I requested the service nor when I complained regarding my problems. In your case, I would try to contact tech support of your ISP in order to get an answer regarding your problems.

By the way, unless you really need to remotely manage your router, I would keep that service out of the WAN interface.
I can't find WAN IP address on ZTE like I can find it On ASUS
On ZTE, only IP I see is that IP Adress in PVC2(Internet)

And what does that IP means?

I agree with this you will require hardening of your device to do this. Which involves generating Private - Public key pairs then using an SSH client with the imported Public key.

PVC1 stands for Permanent Virtual Circuit so you've got two 1 for management using a separate WAN and subnet 255.255.248.0

PVC2 is your ADSL internet.

I see your ISP is using ATM - Asynchronous transfer modulation basicaly ATM circuits use something called a bucket to send data between each virtual circuit node. It's also known as PPPoA or Point to Point Protocol over Asynchronous Transfer Modulation

Not sure if you missed my post or not so I'll try again...

If his router/modem which is the Zxhn-H267n ZTE he can't port forward.

The way it would work is the following.


ZTE port is for example 8443 -> pointed to the internal IP of the main ASUS router -> Port forward that out to the ZTE. This will allow bi-directional communication. Then the Port-forwarding relays that to the internal IP of his PC


ZTE -> Forwards to ASUS router -> Forwards to his PC 192.168.1.192 IF the ZTE cannot forward traffic from itself to the ASUS it won't be possible to communicate over said port.

Just to update this.
While ZTE was in bridge mode I couldn't access ASUS web interface while connected to ZTE router.
But when ZTE is in normal mode I can access ASUS web interface while i'm connected to ZTE.

I still can't access it from another network

I also explained what exactly I want to do and what is not working in that email I just sent to ISP.

I don't really need to remotely manage my router right now, but I want to make this work so I can use it when I need.
And I want to make port forwarding work. I think the same thing is preventing me to do both of these stuff.

All Bridged mode is meant to do is bypass Layer 3 communication.(Correction not the bridged mode I was thinking about) http://help.fluentcloud.com/support/solutions/articles/4000094664-when-to-use-bridge-mode

Basically delegates communication with respect to NAT / DHCP to the ASUS

Translated: your ASUS router ports where completely exposed to your ISP network on bridge mode, which means that you should be able to access your router management page if the service was running on your WAN interface (no port forwarding is required in this case)

If you're using your router management service for testing, that's completely understandable but don't forget to disable it after your test though (believe me, it happens).

I have admin access on ASUS router. But I only have user access on ZTE modem.

It's Killing Floor 2 server that's on my PC.
Ports are 8080 20560 27015 7777 123
I can connect to server from local network, but I can't connect from the internet.
