emoxam commented 1 week ago

Can't find out why routes are not adding. Here's my configs

cat /etc/openvpn/ccd/kostroma

    ifconfig-push 192.168.200.38 255.255.255.0
    iroute 10.1.0.0 255.255.255.0
    iroute 10.1.3.0 255.255.255.0
    iroute 10.1.4.0 255.255.255.0
    iroute 10.1.0.0 255.255.0.0

cat /etc/openvpn/server.conf

    ...
    route 10.1.0.0 255.255.255.0
    route 10.1.3.0 255.255.255.0
    route 10.1.4.0 255.255.255.0
    route 10.1.0.0 255.255.0.0
    user root
    group root
    ...

Why there is no routes from /etc/openvpn/ccd/kostroma ? Is it because of (status=1) ? (status=1) it is bad ? Thank

Is it about https://openvpn.net/community-resources/how-to/#security ? We have openvpn --version

mention enable_iproute2=no maybe that's why route is not working ?
