Hello i'm using this AX 3000 wifi 6 router with tailscale,
having this error if you can find the attached, but i have 0 information about networking and stuff,
i tried to add public DNS like (overwrite local DNS on/off) but nothing works.
could you please help me....
Can try manual change custom DNS server in the GL GUI -> Network -> DNS
Is the Internet access of devices unavailable when you enabled the exit node of tailscale? Please confirm if the GL router has been approved the subnet in the tailscale cental
So I did exactly what you did in GL GUI -> Network -> DNS, then chose Manual DNS and then chose an option (Cloudflare public DNS, that automatically filled the DNS Server 1 and 2 as same values in your screenshot). and the DNS error not visible anymore as you see in my screenshot (but also the DNS is not visible as well)
2)I don't understand your question, Please confirm if the GL router has been approved the subnet in the tailscale cental? how to check on that?
in this screen shot also i see:
This machine has unapproved routes. Review this from the “Edit route settings...” option in the machine’s menu.
maybe this is what you mean in your question
And i fixed that as the sentence say, clicked on Edit Route setting and then approve all routes, i can now connect through my phone
But still when I connect to the router through the main laptop, it does not have internet if connected to the router (Exit node), is that correct, or should still have internet?
bear in mind, that the router is connected to the home wifi, and the laptop is connected to the router, but no internet, while if i use my phone and connect it to the router, it works on my phone if only the laptop run as exit node, but if not exit node, there is no internet on my phone too.
last step: but need to go out for a coffee shop or something to test and see if the public IP address is my home address.
Laptop be supposed to have Internet access via router even if the router connected to home WiFi in home.
But you can go out like shop, hotel, etc. others Internet source, to test if it works.
If not, please share us your topology figure including the laptop, GL router, tailscale exit node devices, etc.
yep I will try that maybe this weekend, but yes in home there is no internet on my main laptop which is the exit node when connected to the router, where the router is connected to home wifi.
so I tried that outside my home, and it works when I connect through my phone and through my friend laptop, but not my work laptop, the problem that i'm not able to connect to the router from the work laptop.
i have same problem from my home when i try to connect the exit node laptop to the router, it does not accept it.
so i don't know what could be the problem
Does your work laptop have a working VPN or some proxy etc. software?
If your cellphone and your friend's laptop are available, so the GL router is working fine with the tailscale exit node.
iptables -A FORWARD -i br-lan -o tailscale0 -j ACCEPT
iptables -A FORWARD -i tailscale0 -o br-lan -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
iptables -t nat -A POSTROUTING -o tailscale0 -j MASQUERADE
Sorry but I don't understand with these, how to do step 1 & 2? and where?
and no I don't have a VPN on my laptop, not sure about proxy, how should I check that ?
my work laptop sometimes we need to connect to VPN for the client or for the company. will this make problem in the future for me?

You may need to check this yourself.
Different VPNs probably have different operating logic. You can check all running software in your work laptop.
Generally it won't be a problem. But it may conflict with Tailscale.
