#Question #HelpWanted - Why "route" is different of "server" in openvpn.conf ?

[jonathan-gatard]

Hello everybody,

I'm new in VPN domain and I'm learning everyday by reading the documentation. However, I don't understand some points:

server 192.168.255.0 255.255.255.0
verb 3
key /etc/openvpn/pki/private/neptune79.duckdns.org.key
ca /etc/openvpn/pki/ca.crt
cert /etc/openvpn/pki/issued/neptune79.duckdns.org.crt
dh /etc/openvpn/pki/dh.pem
tls-auth /etc/openvpn/pki/ta.key
key-direction 0
keepalive 10 60
persist-key
persist-tun
duplicate-cn

cipher AES-256-GCM
data-ciphers AES-256-GCM

proto udp
# Rely on Docker to do port mapping, internally always 1194
port 1194
dev tun0
status /tmp/openvpn-status.log

user nobody
group nogroup
comp-lzo no

### Route Configurations Below
route 192.168.254.0 255.255.255.0

### Push Configurations Below
push "block-outside-dns"
push "dhcp-option DNS 1.1.1.1"
push "dhcp-option DNS 1.0.0.1"
push "dhcp-option DNS 8.8.8.8"
push "comp-lzo no"

Someone can explain me please:

• Why when server is "192.168.255.0" the route is "192.168.254.0"

And also if possible:

• Why the server should be "192.168.255.0", I tried with 10.8.0.0 and it doesn't work (I can connect to VPN but nothing is routed)

My goal is to connect to ssh server located on my VPN client, it doesn't work for the moment :(

Thanks !
