On Linux, you could use a command such as this to NAT the VPN client traffic to the internet: iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE This command assumes that the VPN subnet is 10.8.0.0/24 (taken from the server directive in the OpenVPN server configuration) and that the local ethernet interface is eth0.

Once you have determined your VPN’s gateway, change the routing settings on your computer in a way that forces all traffic to route through the VPN gateway with a command like this: sudo ip route add default via 10.10.11.12 “10.10.11.12” is the VPN gateway in the example above. Replace that string with your VPN’s gateway. On Linux, you could use a command such as this to NAT the VPN client traffic to the internet: iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE This command assumes that the VPN subnet is 10.8.0.0/24 (taken from the server directive in the OpenVPN server configuration) and that the local ethernet interface is eth0.

May 24, 2018 · OpenVPN is a full-featured, open-source Secure Socket Layer (SSL) VPN solution that accommodates a wide range of configurations.

This can allows you to do any custom action like setting DNS, routes etc. But it requires you to store the commands to execute in another file. In order to list routing information the options -n and -r should be provided to the command netstat. $ netstat -nr Add New Route with ip Command. In order to add a new route, we will use the command ip route add by providing related information. We will add a new route to the 172.16.0.0/16 network.

Before using IPsec between the A and B privates network, make sure routing between VPN Gateways of organization is working so that VPN gateway at A side can ping remote side VPN machine (B) which ensures the network connectivity is ok. As shown below, the default configuration of the strongswan tool is inside the /usr/local/etc/ directory.

Mar 01, 2020 · The client has configured OpenVPN server on their network and provided you client configuration file. In that case you only need to install OpenVPN client application to your system and connect to remote vpn network.

OpenVPN is a full-featured SSL VPN which implements OSI layer 2 or 3 secure network extension using the industry standard SSL/TLS protocol, supports flexible client authentication methods based on certificates, smart cards, and/or username/password credentials, and allows user or group-specific access control policies using firewall rules applied to the VPN virtual interface.

Add a new route with: IP address: 192.168.100.0 (the address of my office network; not just one specific machine) Netmask: 255.255.255.0 ; Gateway: 192.168.100.143 (I get the IP from the route table after connection the VPN for the first time). Metric: 1; This command line do the same as the above configuration:

I would normally try doing this by configuring static routing and NAT. The problem here is that I do not have an interfacethat I can use for defining the routes. If I had a VPN server at the MAIN site and VPN client and the CLIENT site, then the VPN client would have some tun interface that I could use to configure what I need.
