Connecting VPN client to private VPN server not loading certain sites

EDIT: SOLVED

I’m using an ASUS AX1800 with an OpenVPN server on my friend’s home network as the VPN server. And am using a GLiNet MT1300 Beryl as the VPN client.

I want to be able to connect to the Beryl client and have my internet traffic come out of the VPN server. It’s mostly working and my IP is showing as the ASUS router IP. However, a majority of websites do not work. Some of these are big names like Slack and Reddit which I’ve noticed doesn’t support IPv6. Websites like Google and Facebook that support IPv6 work. nslookup has only been working on those sites as well.

The ovpn settings are:

remote test.asuscomm.com 1194
float
nobind
proto udp
dev tun
sndbuf 0
rcvbuf 0
keepalive 10 30

comp-lzo yes
;compress lzo

auth-user-pass
client
auth SHA1
cipher AES-128-CBC
remote-cert-tls server
<ca>

RSA keys

Would appreciate any help or ideas on what’s wrong or what to look into

I don’t know what version of OpenVPN you are running on your devices & clients, but some of the parameters in your config are no longer valid in the latest OpenVPN.

I don’t think OpenVPN supports IPv6 either…

Thank you! That was the push I needed to upgrade the firmware on both and it’s working now.

Also I think ipv6 is supported on OpenVPN now
