Hi!

I'm not network / vpn specialist and I am fighting with the below problem.

I'm planning to go abroad in few weeks time and work from there. I'm using laptop with Windows installed (Side A - Client). I would like to have a possibility to connect to my office lan network (Side B). The network provider in Side B does not offer public IP. Therefore, I decided to buy VPS server Centos (somehow side C) and install OpenVPN server on it. The network in side B has a router which has a feature allowing it to work as OpenVPN client.

I set up the OpenVPN server on VPS, generated certificaties and could connect both router (side B) and Client (side A) to the VPS server. However, from Client I could see only VPN address of Router 10.8.0.1 and can't ping Side B network computers which are behind it.

Router.conf

Code: Select all

client
dev tun
proto udp
remote PUBLIC_IP_VPS 1195
resolv-retry infinite
#nobind
persist-key
persist-tun
remote-cert-tls server
auth SHA512
cipher AES-256-CBC
setenv opt block-outside-dns
verb 3
<ca>
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
</ca>
<cert>
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
</cert>
<key>
-----BEGIN PRIVATE KEY-----
-----END PRIVATE KEY-----
</key>
<tls-crypt>
-----BEGIN OpenVPN Static key V1-----
-----END OpenVPN Static key V1-----
</tls-crypt>
keepalive 10 60
user nobody
group nobody

Same for Client.conf

Code: Select all

client
dev tun
proto udp
remote PUBLIC_IP_VPS 1195
resolv-retry infinite
#nobind
persist-key
persist-tun
remote-cert-tls server
auth SHA512
cipher AES-256-CBC
setenv opt block-outside-dns
verb 3
<ca>
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
</ca>
<cert>
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
</cert>
<key>
-----BEGIN PRIVATE KEY-----
-----END PRIVATE KEY-----
</key>
<tls-crypt>
-----BEGIN OpenVPN Static key V1-----
-----END OpenVPN Static key V1-----
</tls-crypt>
keepalive 10 60
user nobody
group nobody

Server.conf

Code: Select all

local PUBLIC_IP_VPS
port 1195
proto udp
dev tun
ca ca.crt
cert server.crt
key server.key
dh dh.pem
auth SHA512
tls-crypt tc.key
topology subnet
server 10.8.0.0 255.255.255.0
push "redirect-gateway def1 bypass-dhcp"
ifconfig-pool-persist ipp.txt
push "dhcp-option DNS 8.8.8.8"
push "dhcp-option DNS 8.8.4.4"
keepalive 10 120
cipher AES-256-CBC
user nobody
group nobody
persist-key
persist-tun
status openvpn-status.log
verb 3
crl-verify crl.pem
explicit-exit-notify
route 192.168.1.1 255.255.255.0
push "route 192.168.1.1 255.255.255.0"
client-to-client
client-config-dir ccd
management localhost 7505

Side A - Client
10.8.0.2
192.168.43.71 ipv4
255.255.255.0 subnet mask
192.168.43.1 default gateway

Side B - Router
10.8.0.5
192.168.1.1 ipv4
255.255.255.0 mask

Side C - VPS
10.8.0.1

What other OpenVPN/OS/router configurations I should put in order to achieve a goal of seeing local machines in Side B from Side A via VPS?
Apologies, if I did not provide You with enough information. Will do so on Your request!
Thank You in advance for any hints!

BR,
Adam.

It is very easy to do that if you know how to make site to site connection , as long as you know making this kind of thing take time and after many try and error you can make it but you need to learn a lot before you can do this .

If you do this for business so it is more faster ask someone do it for you , it work out very quick for you. Just sent an email to TinCanTech so he can help you with fee .
