Eu tenho a mesma configuração do meu servidor OpenVPN desde há dois anos, e apenas copio e colo cada vez que atualizo o servidor. Mas desta vez não funciona mais.
Eu posso me conectar com meus clientes, e posso fazer ping fora da Internet: com nome de domínio ou com endereço IP (o que significa que a resolução do domínio funciona). Eu também posso pingar para vpn servidor ip, ou roteador na rede do servidor.
Mas não consigo navegar na Internet ou dentro da rede openvpn. O único site em que posso navegar é no roteador openvpn (em 192.168.45.1).
Meu conf openvpn:
dev tun
#dev tap0
client-config-dir ccd
local 192.168.45.5 # SWAP THIS NUMBER WITH YOUR RASPBERRY PI IP ADDRESS
proto udp #Some people prefer to use tcp. Don't change it if you don't know.
port 1194
crl-verify /etc/openvpn/crl.pem
ca /etc/openvpn/easy-rsa/pki/ca.crt
cert /etc/openvpn/easy-rsa/pki/issued/server.crt # SWAP WITH YOUR CRT NAME
key /etc/openvpn/easy-rsa/pki/private/server.key # SWAP WITH YOUR KEY NAME
dh /etc/openvpn/easy-rsa/pki/dh2048.pem # If you changed to 2048, change that here!
server 10.8.0.0 255.255.255.0
# server and remote endpoints
ifconfig 10.8.0.1 10.8.0.2
# Add route to Client routing table for the OpenVPN Server
push "route 10.8.0.1 255.255.255.255"
# Add route to Client routing table for the OpenVPN Subnet
push "route 10.8.0.0 255.255.255.0"
# your local subnet
push "route 192.168.45.5 255.255.255.0" # SWAP THE IP NUMBER WITH YOUR RASPBERRY PI IP ADDRESS
# Set primary domain name server address to the SOHO Router
# If your router does not do DNS, you can use Google DNS 8.8.8.8
push "dhcp-option DNS 192.168.45.1" # This should already match your router address and not need to be changed.
# Override the Client default gateway by using 0.0.0.0/1 and
# 128.0.0.0/1 rather than 0.0.0.0/0. This has the benefit of
# overriding but not wiping out the original default gateway.
