This is known as client-side routing. Client-side routing in OpenVPN requires a CCD file for that client containing an iroute statement. It also requires a corresponding route statement in the OpenVPN server configuration file. Consider the following network layout:
What I can tell though is that the alternate routing table (200) is configured to route traffic over the VPN, while the main/default routing table remains w/ the WAN/ISP. So I assume you used either route-nopull or route-noexec to stop OpenVPN from changing the default gateway from the WAN/ISP to the VPN. Install OpenVPN 2.3.9 or higher on two computers. Make sure the computers are connected over a network. For this recipe, the server computer was running CentOS 6 Linux and OpenVPN 2.3.9 and the client was running Windows 7 64 bit and OpenVPN 2.3.10. We'll use the secret.key file from the OpenVPN secret keys recipe here. Jun 17, 2014 · There’s a difference between ALL traffic using the WAN, vs. SOME traffic using the WAN. Policy based routing w/ the GUI creates a new routing table that contains only the VPN as a default gateway. That’s fine as long as the clients you expect to use the VPN only reference IPs that are only accessible via that default gateway. OpenVPN has been integrated into SoftEther VPN, an open-source multi-protocol VPN server, to allow users to connect to the VPN server from existing OpenVPN clients. OpenVPN is also integrated into Vyos , an open-source routing OS forked from the Vyatta software router.
Now we bring up the tunnels. Note the –route-nopull. This ignores routing info from the openvpn server. We want to specify our own routing. Without that, openvpn seems to set our default traffic to go out the last tunnel brought up. If you are having any trouble on this step, run the line without –daemon.

This is one of OpenVPN's hacks to route traffic through your tunnel while maintaining your default gateway. The 0.0.0.0/1 and 128.0.0.0/1 routes take precedence over the 0.0.0.0/0 route since they are more specific while still matching all addresses. Search for "def1" in the OpenVPN documentation for more detail Mar 13, 2017 · 6- Routing Configuration and Starting OpenVPN Server $ iptables -I INPUT -p udp -m udp –dport 1194 -j ACCEPT Enable IP Forwarding in sysctl: OpenVPN and Routing My client can connect fine through the VPN and can ping the gateway but cannot ping any device past that. The VPN client network is a 192.168.4.0/27 network. In my previous post I wrote about how to setup an SSL VPN server on Windows 2012 R2 and enable external network access to the server using OpenVPN.. This article will walk you through the process of configuring IP forwarding on our Windows server and exposing static routes to enable VPN clients to access network devices on the LAN given that Out-the-box OpenVPN will only allow the clients to While the VPN is running (and w/ at least one IP in the policy based routing field), go to a telnet/ssh session, cd to /tmp/openvpncl, and you'll see several files, including openvpn.conf, route-up.sh, and route-down.sh. Post their contents back here (you can block out any personal data).
