I have a OpenVPN server ruining on Unbuntu 14.04 server. Everything works fine, the client connects to the server and can ping the VPN server. I want the client use my internet as it were his internet but I also want to block the client to access my Home LAN. Below is my setup:
Home LAN: 192.168.1.0/24 Router: 192.168.1.2 OpenVPN LAN ip: 192.168.139 VPN Network: 10.8.0.0/24
Server Configuration: proto udp dev tun ca ca.crt cert openvpn-server.crt key openvpn-server.key dh dh2048.pem server 10.8.0.0 255.255.255.0 ifconfig-pool-persist ipp.txt push "redirect-gateway def1" push "dhcp-option DNS 184.108.40.206" push "dhcp-option DNS 220.127.116.11" keepalive 10 120 comp-lzo persist-key persist-tun status openvpn-status.log verb 3
Client Configuration: client dev tun proto udp remote (ip removed) 1194 resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert andres.crt key andres.key remote-cert-tls server comp-lzo verb 3
What I have done is enable packet forwarding
# Uncomment the next line to enable packet forwarding for IPv4 net.ipv4.ip_forward=1
It works but the client have access to my entire LAN.
How can I block my LAN and allow internet traffic to a openvpn client?
