Can't access my asus router's web GUI when connected to vpn

VPN
1

Basically, I can’t access my asus router’s web GUI when connected to Tailscale. I can ping the router perfectly but the GUI won’t load. All of the other services I have can be accessed except for my router’s GUI. I can even access the asus routers/access points from the asus app (only when connected to tailscale though)

I read somewhere that it may have something to do with the firewall? Basically, each time I try to access the GUI, it loads and loads and never ends. Any clues?

Thanks!

Did you setup a subnet router?

Can you please give us more information about how you have tailscale setup in your network

Basically, I can’t access my asus router’s web GUI when connected to Tailscale.

Are you sitting on another remote network (like a coffee shop or a friend’s network)? If so what internal ip address does your client get on that network?

Did you ever sort out the cause and find a fix for this?

Having the same issue.

My workaround is to disable Tailscale on my PC, use an openVPN connection to my NAS con server which is on the ASUS router network and then browse to the router admin panel. That seems to reliably work.

It means that I have to keep the openVPN port forwarding to the NAS.

Bummer

Allow local network access

Yes sorry. I have set up a subnet router for 192.168.13.0/24 and my routers are in 192.168.13.x.

I am not connecting using exit node. I am trying to access my router’s gui using my mabook which is connected to either my iPhone’s celullar data or a private wifi conection outside my house (frend’s house).

I have a ubuntu machine running tailscale in a docker container. This machine is in my local network connected by ethernet.

I guess im not the only one who face this issues

and my routers are in 192.168.13.x.

How many routers do you have on this network?

8

your tailscale docker container is using network_mode in host or bridge mode? also, it may be issue of stateful-filtering and snat-subnet-routes

9

Can you post your full docker compose/command you ran to bring this container up?

The device that can’t access the router

11

The ASUS one, most routers doesn’t allow any address outside private subnets to access GUI/telnet/ssh for security reasons.

12

One router in router mode and two routers in access point mode. All of them Asus

13

host mode! I have no idea what the other stuff means!

https://pastebin.com/MTC9Ryed there you go

15

how can I do that in the asus if I can’t install tailscale on it?

16

What error do you get when you try to go 192.168.13.1 over tailscale? (im assuming your main router is set to .1). Can you post a screenshot of the error from your browser?

I know my dad’s asus router tries to forward me to asusrouter.com when I try to log into it remotely.

17

stateful-filtering basically blocks routes to subnet routes. it also has issues with docker network. you can read more about it here.

18

Are you running the latest tailscale 1.66.4?

19

In the firewall section of the router control panel.

Sure! It just loads forever. There isn’t even an error in the console:
