If you are using Ubuntu machine as OpenVpn Server you can find OpenVpn server configuration either under
/etc/openvpn/server.conf
or
/etc/openvpn/server/server.conf
if you will cat this file it will look something like this
ifconfig-pool-persist ipp.txt
push "dhcp-option DNS 8.8.8.8"
push "redirect-gateway def1 bypass-dhcp"
dh none
ecdh-curve prime256v1
tls-crypt tls-crypt.key
crl-verify crl.pem
ca ca.crt
cert server_3BYLUHGJfabF8i1.crt
key server_3BYLUHGJfabF8i1.key
auth SHA256
cipher AES-128-GCM
ncp-ciphers AES-128-GCM
tls-server
tls-version-min 1.2
tls-cipher TLS-ECDHE-ECDSA-WITH-AES-128-GCM-SHA256
client-config-dir /etc/openvpn/ccd
status /var/log/openvpn/status.log
verb 3
You have to comment ## push "redirect-gateway def1 bypass-dhcp"
and add specific traffic sub net you want to pass through this VPN server like
push "route 10.2.2.100 255.255.255.255" ## some internet server
push "route 54.201.1.19 255.255.255.255" ##example.com
after saving this configuration file now you can restart OPENVPN service
systemctl restart [email protected]
--pull-filter ignore redirect-gateway
?redirect-gateway
line in your client config.--
) or use it when you run openvpn (e.g.openvpn --config path/to/config --pull-filter ignore redirect-gateway
)
