Reverse VPN configuration

illera88

Hi everybody!

I want to ask you for a "simple" thing.
Is it possible to create a reverse VPN connection from computer A against a OpenVPN server B so if I want to connect against A I can do it connecting to B?
Here is the diagram:
B <------------ A

C
So C will be in the A network. Can I do that?
It is easy to do it with SSH using the -R option even binding a socks5 port in B and using that proxy in C to surf as being in A.

Can you refer me to some way to do it? Btw I am root in the three systems (A, B and C).

Thank you 😉

Sort of but not quite the same ...

If you use server-bridge mode you can have your remote client 'C' appear on the same subnet as your server 'B' (eg: 192.168.101.0/24) but it will not be the same IP as your server.

Perhaps that is not quite what you want ?

Hi debbie10t!

Actually that I need is to to launch a program from C as being in the A network because the service I am trying to access its only accessible from A.

Can I do it with this server-bridge stuff?

Thank you for your help 😉

If you bridge at 'B' and VPN 'A' into 'B's' network and VPN 'C' into 'B's' network ... but I don't think that is what you want.

As far as OpenVPN goes .. you cannot make 'C' appear on 'A's' network using OpenVPN.

IE:
Server B: If 'B' is 192.168.88.8 on 192.168.88.0/24
Client A: If 'A' is 192.168.77.7 on 192.168.77.0/24
Client C: If 'C' is 192.168.66.6 on 192.168.66.0/24
Then: OpenVPN Cannot Give 'C' and address on network 'A' such as 192.168.77.99

that is precisely that I wanted to do... :/

Any other idea to do it? Thank you for your help
