My 24/7 vpn that I run doesn't filter all traffic, only a specific website that's blocked where I live.
The .ovpn client config that I use (and it works in Tunnleblick and OpenVPN app in iOS) is below:
Client Config
client
dev tun
proto udp
remote SERVERIP 1194
resolv-retry infinite
nobind
route-nopull
route 151.101.0.0 255.255.0.0
route 52.34.230.181 255.255.255.255
route 52.203.76.9 255.255.255.255

persist-tun

There's no way to simply run a .ovpn file directly on my router. But it has a OpenVPN Connect page with options, like this:

And the Router key/cert page is like this:

I'm very new to this. And I'd really appreciate the help

And here's the config from my server if that's needed as well:
serever.conf
local 10.0.0.4
port 1194
proto udp
dev tun
ca ca.crt
cert server.crt
key server.key
dh dh.pem
auth SHA512
tls-crypt tc.key
topology subnet
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
#push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 10.0.0.100"
push "dhcp-option DNS 1.1.1.1"
keepalive 10 120
cipher AES-256-CBC
user nobody
group nogroup
persist-key
persist-tun
status openvpn-status.log
verb 3
crl-verify crl.pem
explicit-exit-notify
Please let me know what I'm doing wrong in my router page that vpn isn't connecting. Cheers!
And a second question about the server. Is having push dns option in the server.conf better than having it in the client .ovpn file? (I run a Pi-hole when connected to home wifi)
