Setting up VPN for so that every computer has same public IP as the main computer

VPN
1

I am not sure I have even worded that correctly, I just need to be pointed in the right direction and I can research more from there.

I’ll explain in more detail…

Let’s say my public IP of my work network is 71.233.91.127. I want to set up a VPN on my work network so that when I connect a computer to the work network via VPN, its public IP address will also be 71.233.91.127

Is this possible? What service do I need to look into? I was thinking VpnBook but not sure if that is what I need.

If this is not possible, then I assume it would be possible to make them all have the same public IP address but the IP address would be different from the one mentioned above?

Thanks in advance. Not looking for anyone to do my work for me, just looking to be pointed in the right direction. Of course, I need this to be as secure as possible since it will be moving personal data.

Most routers do NAT and so all devices on the lan will be routed out a single public IP on the internet. The router can host a VPN server itself or you can forward the incoming ports needed for a separate vpn server on the router and all devices will get out the same public IP.

What do you have for a router/firewall currently? This is normally called full-tunnel (also disabling split-tunneling), where all traffic from the client is sent over. Almost any business/enterprise firewall would support this

probably should look at something like an ipsec/l2tp server on your office firewall then connect to that from clients with the “send all traffic” option. mobile devices tend to send all traffic by default.

Sounds like you just need to turn off split-tunneling and you are good to go.

OpenVPN?

​

Redirect Gateway is what you are searching for.

​

Everything your client wants to reach has to go through the tunnel, your Router at work, and the Internet Connection at Work.

I’m sorry if I sound rude but wouldn’t that just be a regular NATing needed and a full tunnel vpn to make sure that all the traffic is going trough the vpn?
Or do you mean that you’re going over a l2l tunnel? I understood it as a webvpn for clients.

Yes, you can have the remote computer use the VPN server’s public IP if you use it as a gateway. This setting will vary based on the VPN client or server. In Windows 7 for pptp connections, it was a checkbox.

Be mindful of IPv6, though…those may leak and can uniquely identify your device.

I think I need to set up and host my very own VPN server. What services can be used for that?

11

Basically I want to whitelist the networks public IP address so that I can keep a certain website inaccessible to everyone other than the network. And then have users connect to the network via VPN so that they can have access to the website even when away from the office. Im not sure that what you suggested will help with that, will it?

You need a device to run the VPN, ideally a router or firewall, although for a small deployment a server could do the job too

I like softether personally but OpenVPN is popular and has better support/documentation
