I have a Huawei Mediapad T5 which is connected to the VPN wireless on Netgear R7000 running DDWRT. I have checked all other devices which include PS5, iPhone, Laptop and desktop running Linux, Android TV box all show the VPN address but not the Huawei Media pad T5 shows my real ip for my isp and not the VPN. I have tried to restart the Huawei Media pad T5, deleted wireless network both 2.4 & 5 ghz with the same results. Webrtc is is disabled on the Firefox browser.
If I connect through open vpn or my vpn client, it works but if I disconnect it, real up shown even though the ddwrt is on vpn. All other devices do not have this issue and anything connected to the ddwrt shows the vpn ip.
Can anyone help?

dd-wrt is on *what* VPN? OpenVPN? PPTP? WireGuard?

What are using to verify the public IP? Some website? Like http://ipchicken.com?

If using OpenVPN, are you using PBR (policy based routing) on the dd-wrt OpenVPN client?

Apologies, when I connect the tablet using open VPN for android which is installed on the tablet, the VPN works but when I disconnect that and connect to the WiFi on the DDWRT router which has VPN running, my ip is shown. All other devices the VPN works fine when connected to the WiFi on the DDWRT router.
In other words, the only way to have VPN on the tablet is by using open VPN Android which is installed on the tablet. I hope this now makes sense.
Apologies if I broke rules with this post by posting in the wrong category.

I am using www.dnsleak.com and www.whoer.net and www.ipleaks.net

You did not break any rules so no need to apologize

The important questions from @ eibgrad still needs answering.

Are you using Policy Based Routing?
Because that is how some of your clients can use the WAN and others the VPN.

If not then all attached client must use the VPN and if a client does not then check if it uses your wifi or perhaps someone elses, also check if the VPN on the client is indeed totally switched of otherwise it could connect to something else than your router is connecting to.

To test add a killswitch to your router to stop traffic going out of the WAN.

Test this from the CLI (telnet/Putty):

I am not using policy based routing but to be certain, how can I check this?
I have checked and it is using my wifi. I even deleted all wifi and added them again and had ro enter the login details for the wifi.VPN is switched on and working:

How do I add this command iptables -I FORWARD -o $(get_wanface) -j REJECT
Firewall is off.

[egc]

I hope your firewall is not really disabled.

The instructions are actually in my post

Test from command line interface (telnet/Putty or what ever you like)

And if it works or if you have no idea what I am talking about place in Administration/Commands and Save as firewall

To be sure this is a normal setup where the router is in gateway mode and the WAN port is connected to the ISP modem?

[manchesterblack]

The DDWRT is in router mode and the WAN port is connected to the ISP modem.
I know how to do the commands. Should I still excute? I have wired connection for my TV and PS5 on Lan1 and Lan 2.All the rest on wireless.
Firewall is on.
VPN is on.

[egc]

A kill switch is always a good thing


When you say the router is in router mode I hope you are not referring to the setting of "Operating Mode" on the Advanced Routing Page that should be left in "Gateway"

[manchesterblack]

I tried the command and saved firewall and lost connection because the main router has a cable which is connected to the WAN port of the DDWRT router. The VPN is now not working on all devices connected through wifi apart from a linux laptop. Before the iPhone was not showing my real IP when connected to the DDWRT router wifi, now it is doing the same thing as the huawei pad.

[manchesterblack]

No one seems keen to help not sure why

[egc]

Because you are not providing enough information.

As you have been tinkering a lot with the router consider resetting to defaults and only do the minimal setup (manually of course do not restore from a backup file)

Provide details about your network setup. if you followed a wiki what wiki did you follow.

If you are setting up a VPN client what instructions did you follow? For OpenVPN see:
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=327398

Post a picture of your OpenVPN settings page (whole page including everything in the additional config.

Post a picture of the OpenVPN Status page whole page

This issue has been resolved, I am not sure how but this is what I did.
1. Flashed DDWRT DD-WRT v3.0-r46788 std (05/28/21)

from scratch.
2. Set up the router using save, next setting, save and then when I have finished that is when I hit Apply and reboot the router.
