no internet with OpenVPN server

[IronJeff]

I'm running 384.5 on an ASUS RT-AC87U, and I've setup an OpenVPN server. I setup some very basic ad-blocking rules for dnsmasq, and the OpenVPN server is set with "client will use VPN to access" "Internet Only".

In the Advanced settings, I have "advertise DNS to clients" set to "yes". Whenever a client connects to the VPN server, it is not able to resolve any IP addresses.

If I set "client will use VPN to access" "both", then DNS resolution works fine. It's a workaround, but I don't really want to enable outside access to my LAN, even through VPN, at this time.

Any ideas on how to get this working?

That's because your router is configured as your LAN's DNS server. If you set your clients to only have access to the Internet, they can't talk to your router's DNS server.

Oh, that makes perfect sense. But I had it configured as internet-only in older versions of merlin, and it worked fine. I guess that “bug” was fixed?

WAN-only and LAN-only were a bit quirky indeed in the past, so it's possible it was working tho it shouldn't have. Disable the DNS setting, and let your clients use their existing DNS servers instead.
