Thank you very much Sir, this tutorial is very useful for me :)

[@VanTechCorner]

Glad it was helpful!

[@balalakshmiar9456]

A great tutorial. Thanks a lot.

[@VanTechCorner]

You are welcome! You can check out other OpenWRT tutorials on the channel as well.

[@VanTechCorner]

Glad you enjoyed it!

[@Pkemarco]

Hi ! Thanks for the video ! Do you plan to do another video on the lastest version of OpenNDS ? Because many things have changed I feel. Thanks again !

[@bankasn8800]

nice tutorials bro. nice for school and campus hehehehe

[@cuongphan8881]

Thanks anh Van Tech chia sẻ, Nhưng không biết OpenNDS có thể sử dụng trên 2 network interface với 2 giao diện hiển thị khác nhau được không anh ơi?

[@imtrue2132]

Great tutorial. The main issue in this video is the captioning. The English is missing/inaccurate. It has a lot of Vietnamese and English mixed up and inaccurate words. Check the CC. For the Deaf and Hard-of-hearing under us.

[@VanTechCorner]

Hi, thanks for the feedback. I will have to manually review the caption and update it.

[@ahoj113]

Genius :)

[@centlytical]

Why when i edit something on vi /etc/config/opennds Example the gatewayinterface seems not applying or doesn't do what's supposed to do.

[@mahmoudlouati7700]

Thanks for this tutorial! It was very helpful. But there is a problem for me opennds isn’t working and I don’t know why? Shouldn’t we add a firewall rule allowing the 2050 port which is the opennds gateway port?

[@TradieTrev]

Fantastic tutorial, the only constructive criticism I have is that the console text is too small. Thanks regardless!

[@VanTechCorner]

Thanks for the feedback. The default font size on Putty in 10 and I increased it to 12, but looks that the text is still small if watching from a mobile device. Are you watching from a smartphone?

[@TradieTrev]

@@VanTechCorner in 720 on an old TV with hdmi input, she only does 1024X768 resolution so I'd expect the same mobile.

[@ciberconntrol]

Interesting and well explained. I have a unifi ac lr openwrt i use as client mode at a hotel captive portal but when connecting shows me login address in chrome but no splash or logging option I installed travelmate opkg but not working can you advice ? thank you

[@reycoseguma2184]

Very good tutorial. Can make a tutorial for Forwarding Authentication Service (FAS) of OpenNDS?

[@ricardoenrik]

Thank you very much for the tutorial! A question, what router do I need to install opennds package, I have a tl-wr740n and opemwrt 18.06 but doesn't download nothing, can you help me please? And sorry for my terrible English xD

[@billhoma6092]

I would like the splash page to only be an informational message. Therefore no internet access and the continue button would terminate the session and release the DCHP assigned. How would I do that? Thanks. I love your OpenWrt tutorials.

[@vishalsharmahacks]

What hardware you used to perform this , Nodemcu ?

[@jeftesilva301]

Hi. I really appreciate your work and I have learned a lot from your Openwrt tutorials. I recently upgraded my router, an Archer C60 from TP-Link, and replaced EEPRON with a 16 MB one. However, OpenWRT does not show this Upgrade. I've tried to see several tutorials and I can't see a solution. Can you help me? I think it would be a great topic for your discussions on your KZbin channel. Thanks.

[@VanTechCorner]

Hey, thanks for the comment. I haven't try to upgrade the flash chip before. Maybe I will try to do it once I have a chance and will make a video about it. Thanks for the suggestion!

[@alexcool8980]

Hi, thanks for the usefull video! Is it possible to add authentication to the page? Like a radius server?

[@VanTechCorner]

Yes you should be able to do that. With OpenNDS and other packages.

[@qlpqbbhdqz6509]

What a genius! Thanks for the tutorial ..how do we add password and voucher for the guest wifi?

[@YoutubeWatcher264]

Does this stop Mac address spoofers from connecting to the wifi?

[@anitbehera5651]

Hi Van Tech, The latest version of openNDS doesn't have legacy splash option, could you please guide or make a new video how to edit splash pages.

[@VanTechCorner]

Hi, can't promise the time but I will definitely look into it.

[@shaharblank98]

@@VanTechCorner I have the same issue now, it seems that this video is no longer relevant after some last updates to OpenNDS, and now the legacy_splash_option is no where to be found, so I couldnt edit the splash page and make it my own html page, help? :(

[@damh1192]

Could you do a tutorial on rtty zhaojh329 for remote access to routers with Openwrt

[@user-ec4xm2rg5e]

Hi Van Tech. Very usefull video for my lab. I would like to enable Captive Portal on the same router for wired guests (ethernet PC), like for wireless guests as well. I need your help, I am a beginner. Thanks in advance.

[@minseok1744]

hi,sir is that possible just to make the captive portal work on the lan 3,4 port,so the 1,and port 2 can connect with no captive portal?

[@HeinserTorres]

yes bridge interfaces.

[@babatundesalman8297]

Where is the first part of this tutorial please. I'm lost.

[@mdsaim4305]

how to whitelist some users in wifidog?

[@Dhanuhammer]

Is it possible to have a normal Wifi router on another floor, and have captive portal on openwrt router, and link both through VLAN, and display captive portal to users who connect to the normal Wifi router?

[@VanTechCorner]

Nope you can't do that. This package will only run on the OpenWRT router.

[@johanna-bapt.martaasaeda9499]

@@VanTechCorner But if the normal router is in IP-Client mode (i.e. Access point mode), then it would work, right? I think that's what @Dhanuhammer is trying to do.... well, the question is a year ago, though.

[@diegofelipeherreracleves5244]

What about ssl and no internet access

[@elmanaro]

HELP! How do I generate a random password for every new user?

[@sunilalw7m]

I don't have physical settings tab, where I need to find, I am on the latest openwrt ver 22.03

[@VanTechCorner]

Thing changed in the recent release. You can take a look at my "guest wifi openwrt 21.02" tutorial and continue the setup.

[@sunilalw7m]

@@VanTechCorner I have a static html website, I want to host it my openwrt router and configure guest or new access point to access thease webpages only, if they try to open any site, they should redirect automatically to static webpage url, rest access points and lan should not be impacted. I am new to openwrt, could you please help me to achieve it? Thanks

[@VanTechCorner]

You can see my Captive Portal video, or research about OpenNDS

[@hungnguyen-dr8mr]

look like you're from Vietnam :D

[@VanTechCorner]

Yes I am

[@tompointdll]

Awesome video ! Sadly, it didn't work for me, openNDS never opens the login page, either on mobile or on pc Edit: After some thinkering, it works !!

[@VanTechCorner]

Cool, glad that you get it fixed.

[@lamseuyoan-m123]

Can you show how to configuration hotspot

[@VanTechCorner]

Hi, this video was made year ago and I didn't keep the config file with me.

[@user-mc8cj3ls6m]

That router is Unifi Malaysia? I thought this channel based in Vietnam?

[@VanTechCorner]

Yes it is. I started this channel when I were working in Malaysia.

[@user-mc8cj3ls6m]

@@VanTechCorner Oh i see thats great to know! May i know if Unifi Malaysia PPPOE will work with modified (OpenWRT) router? I’m from Malaysia :)

[@VanTechCorner]

Yes of course, you also use Mikrotik and Edgerouter as well, as long as the device supports VLAN configuration. You can go to our group in FB and ask other users who is in Malaysia.

[@shaharblank98]

How can I open this terminal window at 4:45?

[@VanTechCorner]

Use Putty or other CLI interface to establish the SSH connection to the router.

[@VanTechCorner]

This is a very basic procedure to manage OpenWRT, you can see how it looks like here kzbin.info/www/bejne/jImVgYywfLKhqsU

[@shaharblank98]
