Privat Site-to-Site VPN

ravn83

Hello together,

i searched a lot in this and other forums for a solutuion of my project.
Now, i want to collect the ideal way th get what i want to do.

The Project:
I want to connect my Network with my parents network (and mybe later my brothers and sisters network).
My base is a raspberry pi. at my network i have a pi 2b with raspian an pivpn.
On my parents side i have the same.
As next, i want to configure a dns server, which redirect connection through the vpn tunnel (on both pi´s with static routes).
And i want to connect mobile devices also with the vpn client to the hole network.

My Questions:
1.How can i connect 2 network like side.to-side?
i read that i need to connect two networks a pi as a server and another as a client ans static routes in linux kernel and the router

2. Can i run a pivpn server an also a openvpn client?
the reason is, i want to connect the pi with the client to my network and give my parents the availability to connect via vpn to their own network, indipendently from my vpn connection

3. how can i configure a dns server on the server side to connect the dns services on both routers?
is this possible? or do i need a dns service on each raspberry pi and to configure them as primary dns on the routers dhcp?

4. which configuration ist the best for security / performence?
my network is a 200mbit/s Down-/50mbit/s upload connection, my parents connection is 200mbit/s down- / 10mbit/s upload.

thanks a lot guys.

best regards
ravn

Yes.

Openvpn comes with a considerable learning curve so you will need to read a lot of documentation.

Yes but it complicated. I suggest you start with the basics first.

No doubt this will be a more serious issue than you realise. Again, start with the basics ..

There is no such configuration.

The Openvpn developers set the defaults to what they believe are both secure and perform well.

Again, start with the basics ..
