How do I connect to a Network using OpenVPN?

I have been attempting to follow instructions in How to secure a home network with OpenVPN?

, but I can't seem to get an SSL/TLS connection working with OpenVPN. My Windows OS on the vista machine can connect just fine. My Debian OS in the client can ping other machines on my network and connect to one, but not others.

Is it possible to use OpenVPN with SSL/TLS? Is there something I am missing or wrong in my OpenVPN config? Any hints would be greatly appreciated. It is possible, but rather not trivial. You will have to use some extra tunnelling capabilities of OpenVPN on the server. Specifically you would have to set "tun-mtu", "mssfix" or at least "reducemss" and "sendwindow". You will also need to run the OpenVPN client as a client application and not as a service.

There's some good documentation available here: As a note to add, although this isn't directly related to your question, and this has been covered somewhat before, but a quick search for openvpn TLS will give you several interesting results (which may be duplicates in some way).

How do I set Routing in OpenVPN server?

I have set OpenVPN server using this command.

sudo openvpn --config /etc/openvpn/server.conf --daemon After this, I have started the service using sudo service openvpn start, but I am not able to access internet. I can ping 8.8 and www.google. I need a proper step by step solution to access internet.

I have tried this, but no luck. Sudo openvpn --config /etc/openvpn/server.conf --route From the OpenVPN server man page: Add routing information to the client's routing table. This is the default when a client is started with the --client flag. You will have to specify a --route command line option if you do not want routing to. be handled automatically for you. The "--route" command line option requires the --client flag. For more information, see openvpn(8).

How do I connect my Mac to OpenVPN?

This is a complex process and it will depend on your computer's configuration.

If you have only one Mac machine, or if you have multiple Macs connected to the same router, you can connect directly to the OpenVPN service's website with no further setup required: go to and click the Join Now button. Once there, you'll be asked for your username and password (again, you must have a US-based email address to sign up). The following instructions apply when you have a single Mac computer. To make things as easy as possible on other setups, this is how you're going to install a client on your computer. I suggest using a Mac mini with OS X 10.8 (Mountain Lion) or later installed, along with a USB 2.0 port on your Mac.

Step 1: Install a server. You need to be able to accept incoming connections to your OpenVPN server from other VPN clients. This makes perfect sense when connecting over the internet, and it will make sense when you add more Macs. You have three options for installing an OpenVPN server:

The easiest method is to download a recent version of openvpn-server-2.tgz from the OpenVPN Server site, save it to a USB flash drive or external hard drive, and install the client from that. You don't need to modify the package at all (aside from configuring the server in /etc/openvpn/easy-rsa) before installing.

If you already have an existing user account on your Mac that will run the OpenVPN server application, you can simply transfer the application, files, and data from that account to the new OpenVPN server installation. Assuming the new installation is going to run on a local machine, your best bet is to do this through File Sharing (preferably under System Preferences > Shared Folders > Advanced), as the openvpn application does not support drag and drop. To get to Shared Folders, open the Utilities menu and select Open Shared Folders. Open Shared folder. In the navigation window that opens, select Preferences, then click the tab with the word Advanced.
