How to only route specific traffic through VPN
Posted: Tue Jan 31, 2023 5:50 pm
Hi, I've setup a VPN to securely access remote servers but have found that all my traffic is being routed through the VPN instead of just the traffic I've specified. I've added route and route-nopull lines to my config file but am still having this issue on both OpenVPN Connect for Windows and Tunnelblick for Mac. Can anyone see what I've done wrong here? My config file (minus certs) is shown below:
client
proto udp
explicit-exit-notify
remote <IP redacted> 1194
dev tun
resolv-retry infinite
nobind
persist-key
persist-tun
remote-cert-tls server
verify-x509-name <redacted> name
auth SHA256
auth-nocache
cipher AES-128-GCM
tls-client
tls-version-min 1.2
tls-cipher TLS-ECDHE-ECDSA-WITH-AES-128-GCM-SHA256
ignore-unknown-option block-outside-dns
setenv opt block-outside-dns # Prevent Windows 10 DNS leak
verb 3
route-nopull
route 10.0.0.0 255.255.0.0 # CIDR range of my remote servers
