tunnel openVPN connection <-> proxy SOCKS

willy87

Hi guys! I would like to try to tunnel my openVPN connection over a SSH connection to be used for a proxy SOCKS.
I have:

-server.conf running on my dedicated VPS
-putty on my tunnel win work pc (it uses http proxy for surfing the web)
-client.ovpn for client device iphone

I read many tutorials and pages but the issue is not so easy.. Could you help me?

For example I only know that port 443 need to be used in putty to reach my VPS as tunnel SSH.
I don't know so wich port I may use for openvpn connection..protocol..

Can I estabilish a openvpn connection from my iphone (client) (thanks to openvpn official app) to my dedicated VPS (server) through putty work pc tunnelling? :?:

thanks guys to help my in this project!! :mrgreen: :mrgreen: :mrgreen:

I just wrote an article on this: https://www.comparitech.com/blog/vpn-privacy/hide-openvpn-traffic-with-ssh-tunnel/

For more detailed troubleshooting you should post your configs and logs from server and client.

Hi! Thanks pabischoff!

looks here please

server

port 1194
proto tcp-server
dev tun1
ifconfig 10.4.0.1 10.4.0.2
status server-tcp.log
verb 3
ca ca.crt
cert server.crt
key server.key 
dh dh2048.pem

client

client 
remote localhost 1194
port 1194
dev tun1
redirect-gateway def1
ifconfig 10.4.0.2 10.4.0.1
socks-proxy-retry
socks-proxy 127.0.0.1 8080

i receive from log this error:
option error:remote option not specified..
I tried to modify socks ip.. remote ip.. add "client" at begin but nothing..

Just for your info I already set in work pc the putty software with tunnel on port D8080 and for necessary HTTP proxy 8080 (same port)
I try with pc browser and if i set socks proxy localhost port 8080 i can surf correctly under tunnel. So puttytunnel is working fine.

We just need to set connection from client iphone (i use openvpn connect) and my dedicated VPS in debian where server.conf is running 🙂
Thanks for helping me..

If you have better idea to surf with my openVPN from my iphone i will really happyy!!!! :mrgreen: :mrgreen: :mrgreen:

EDIT: I write again client.ovpn and now should be ok.
But i cannot connect because i receive error regarding localhost
I try also to set

socks-proxy-retry
socks-proxy 172.27.153.206 8080

(172.27.153.206 is work pc ip where tunnel is on)

thanks for helping guyss

I could be wrong but I think you need to set your cert, secret, and ca files in your client config the same way as your server config, and make sure those files are in your config directory:

ca ca.crt
cert server.crt
key server.key

That might be why it's rejecting the connection. You can also try appending the contents of those files to the end of the client config: https://forum.pfsense.org/index.php?topic=86914.0

A server log would help.

It’s probably no surprise that streaming services have seen a huge boom in the last five years or so. To accommodate the increased interest in the online consumer market, streaming services have expanded their range of services. how to change movie language in hotstar
