MT6000 Captive Portal Setup

Routers
1

Hi,

I've been searching on a way to setup my MT6000's Captive Portal. Basically, I just want a landing page for my guests (Guest WiFi) every time they connect to my SSID, and setup how many lease time/minutes they can connect each session.

I saw a doc regarding this: Setup Captive Portal - GL.iNet Router Docs 3 - but this option is no longer available on MT6000 or has it been discontinued?

Or can someone suggest any alternative to it? Do I need a plugin etc? Thanks!

Firmware: OpenWrt 24.10.0-rc2
Flint 2/MT6000

Hi,

Yes. The captive portal feature has been removed from the GL router.

If you need to use a captive portal, consider using other plugins, such as nodogsplash

After installing the plugin, if you cannot enter the Luci page, you need to add a command to the nodogsplash configuration file.

list users_to_router 'allow tcp port 8080'

Thank you for this response. And after days of tinkering around, I managed to make it work. There's however a catch.

So, I set my lan2 interface as my guest network. I connect another router/switch to my lan 2 port (it's an outdoor access point) for my guests and everything is working fine firewall wise etc.

However, when I installed this plugin, yes I managed to make it work specific to that port or device only by setting the gateway interface to lan 2:

However, the issue now is this switch/router can access my LAN. The thing is, If I don't switch the firewall for guest to lan whenever someone connects to my guest wifi, the captive portal shows but there's no webpage. And removing the firewall from guest to lan fixed the issue. I was thinking there was just some kind of permission firewall issue to access the web files.

So the issue now is security. They can access my LAN admin GUI, even access Luci etc. A few days ago someone try to cast to my TV and I know it was just a guest. The firewall mitigated those issues for me. Hence making lan2 as my guest etc.

Anyway, I'm sorry for the confusing statements I'm not that advanced user so please bear with me. Is there a way for me to still block them accessing my LAN or bring back my original GL firewall + make the captive portal working? Thank you

You connect the LAN2 port of the router to the outdoor.

You can try to use firewall rules to restrict the traffic of this interface from being sent to other LANs. For example:
iptables -I FORWARD -i lan2 -o lan -j DROP

If after configuration, devices on LAN2 cannot access the Internet, you can trying allow necessary traffic for LAN2 and permit access to the main router (192.168.1.1) to obtain the gateway, DNS, etc.

iptables -I FORWARD -s 192.168.9.0/24 -d 192.168.1.1 -j ACCEPT  

iptables -I FORWARD -s 192.168.9.0/24 -p udp --dport 53 -j ACCEPT  

iptables -I FORWARD -s 192.168.9.0/24 -p udp --dport 123 -j ACCEPT
