Hi


I successfully created a vpn connection to two pcs


but I don't know how next to logon to the remote pc.


I thought to use RDP or should I use other software.


The point of using VPN is to not have an RDP open port.


Thanks


Ford

You can use RDP as the port won't be forwarded through Router, but open only to your internal network. You can create a firewall rule on each machine to allow connection only from that VPN subnet.

The problem is really making sure only trusted devices connect to the VPN.

Is the answer to your question, you will now RDP in on the private IP address of the machine, rather than the public?

 

...not really sure what the question is.

and now you have to open other ports for SECURE VPNs :-)
VPN wont let you login to the other PC, only access its files , if shared

Are you trying to share files, or actually login to the remote PC itself ?
You can setup non standard RDP ports and set the firewall/router to only allow port access from a specific external static (internet) IP
Or use Teamveiwer etc .

Is allways SOME risk .

I think there's stuff to do even before this. IIRC the OP's network was twice compromised (once server, another endpoints) with cryptolocker malware. Before opening up remote access (regardless of VPN or not) this should be well secure before anything else progress.

 

Once secured a VPN will require port forward at some point. The RDP protocol is usually secure if proper password checks are implemented. By creating local firewall rules (on each server) to allow RDP inbound from the VPN subnet only it will reduce the risk of outsiders connecting.

 

Obviously there are other considerations - what kind of VPN has the OP implemented? If PPTP then it's the same as not having any VPN at all. OpenVPN is ok but slower than L2TP generally. Who has access to the VPN?

 

There is a lot to consider when giving external access to systems.

Thanks

 

Yes we are wanting to remote into the PC itself.

 

I will do some test ones first away from the network, because I see there are lots of security factors to consider.

 

The security has to be as tight as I can get it without making the thing unaccessible.

 

I'd rather a hardware firewall or gateway.

 

I'll report back later.

 

Thanks for the suggestions, I'll take those on board and consult my comptia security books which I wish I had had the time to learn prior.

 

I'll set up a bit of a lab

Teamviewer with 2FA enabled for the account and individual passwords for each PC. No need to port forward anything and you will be safe.

Thanks

 

That is what we have decided to go with

 

In the meantime I'll work on the security labs and post some updates from time to time.

 

That might be useful for some people.
