Very Confusing is OpenVPN Setup

viragomann

The clients LAN must not overlap the remote LAN, least of all it can be the same subnet. If so it's not possible to access the remote site.

I've never seen an empty routing table on a device which has internet access. There must be at least one gateway and one route.
When a OpenVPN connection is established and a route is pushed by the server to its LAN network, you should see this route pointing to the servers IP, probably 10.0.8.1, as you mentioned above you can access pfSense by that IP.

@viragomann again my apologies - my local LAN is 192.168.1.1/24; the LAN I am trying to remote into is 192.168.0.1/24

rwhitney

I am attaching a screenshot:

this is the default gateway and the Static Routes table is again blank

viragomann

The routing table is the key here, but that one of the client!

rwhitney

@viragomann How do I display the client routing table or which one do you need to see?

rwhitney

@viragomann does this help?

Derelict

The first step to configuring a VPN is understanding what it is you are actually doing.

On the client, connect the VPN. Then print the routing table.

Some common command lines:

Windows: route print
Mac: netstat -rnfinet
Linux: netstat -rn4

You can use Diagnostics > Routes in the pfSense software.

@rwhitney said in Very Confusing is OpenVPN Setup:

I have set the route LAN network to 192.168.0.1/24

That should be 192.168.0.0/24 in the local subnets field. Unless you have set Redirect IPv4 Gateway in which case that should be not set anywhere as everything is routed.

@Derelict please pardon my dust as I AM learning!

@stephenw10 setting it to 192.168.0.0/24 does not seem to make a difference - I did have it set to Redirect IPv4 Gateway, but have removed that

rwhitney

Just to indicate my gratitude to everyone who has offered advice in this thread - thank you! (I am not yet connected to internal LAN however)

stephenw10

It's still sending route all and not just 192.168.0.0/24.

Try restarting the server end to be sure that new setting in place and then check the Windows client routing table.

Steve

rwhitney

@stephenw10 so reboot the netgate server? I will have to wait a couple of hours first

Derelict

No. Restart the OpenVPN process. (Status > Services, stop it and start it. This is restarted when you make a change like disabling the redirect gateway push but Steve is just being thorough.)

rwhitney

@Derelict I just restarted the running process for openvpn. I did just notice that I am getting a connection error: key registration failed to occur within 60 seconds... I am trying this from a Windows laptop at work through an external wirelass network. I don't have this connectivity problem from home on my linux box - just from there I still cannot see the local LAN here at work. All I can see is the firewall

rwhitney

@viragomann Here is my server setting for Tunnel:

I do not see a setting for Remote Network in OpenVPN > Server

viragomann

@rwhitney
That was wrong. It should be "Local Networks".
I'll correct it above.

rwhitney

@viragomann Oh, so I do have something correct?!!

viragomann

@rwhitney
Yeah!

rwhitney

@viragomann
If I were to start from scratch, what would be the first thing to do? (setup the Cert?)
second: setup an openvpn server: (I think I have this set).
Third: setup a user?
Fourth: setup a user cert?
Fifth: download config from Client Export
What am I missing?
