I'm trying to set up OpenVPN on my Asus RT-AX55 router. It seems fairly easy - enable OpenVPN, download config files, and it should be good to go, right? Well, the initial setup had old and insecure encryption keys, so I had to generate new ones and update those using the GUI. Granted, it WAS possible to override the warnings in client apps, but I've already had done certificate generation for OpenVPN in the past so that wasn't that big of a deal.
With the updated certificates it seemed everything was going fine - I could establish a connection (both from a Windows 10 client as well as my Android phone) and access network resources (routers WOL page + access my PC over RDP). However I also wanted to use this connection to access the internet in a secure way (ex, from an open hotel WiFi or something of the kind). And here, it turns out, the router's not working as it should. The whole thing is VERY strange.
All of the following statements are true when connected to the OpenVPN on the router. I've tested these things mostly on a Windows 10, but similar stuff's happening on the Android phone, which suggests a configuration / router issue.
1) I can resolve DNS names fine (NSLOOKUP points to the router as the DNS source and it responds to queries)
2) I can ping internet addresses (assuming they respond to PINGs; something like MS Azure Portal does not)
3) I can access sites by their IP address (I can open https://1.1.1.1)
4) If I attempt to access a site by URL... I get nothing. Same is true if I attempt to get the raw data using something like Invoke-WebRequest from PowerShell.
The configuration seems fairly standard. The firmware itself recognizes my settings as "Internet and local network" under the "Client will use VPN to access" setting. I've also managed to set up the IPSec VPN, and that works fine all the way through (but I'd rather use OpenVPN since setting it up is much easier).
Did anyone have similar issues with this router model? Or perhaps similar issues in another router model? Any ideas what could be the cause and how to fix this?
