How to send traffic to only one domain through OpenVPN?

Question

openvpn

Now the server has this config:

push        "redirect-gateway def1 bypass-dhcp"
push        "dhcp-option DNS 8.8.8.8"
push        "dhcp-option DNS 8.8.4.4"

On the client like this:

client
proto                 udp
dev                   tun
remote                {{ public_ip_address }}
port                  {{ vpn_server_port }}

resolv-retry          infinite

remote-cert-tls       server
auth                  SHA256
cipher                AES-256-CBC

pull-filter           ignore "redirect-gateway def1 bypass-dhcp"
route                 10.0.0.0  255.0.0.0
route                 172.0.0.0 255.0.0.0

ignore-unknown-option block-outside-dns
block-outside-dns
verb                  4

persist-key
persist-tun
nobind

What needs to be added either on the client or on the server so that when accessing the example.com domain, the traffic goes through the VPN gateway?

Answer 1

route add - domain - gateway
and do not forget to set the metric above the main connection
