#HOW TO USE OPENVPN ON MAC MAC#

This means that we need to temporarily push all traffic through the VPN while we work with that AWS resource.ДЄs a Mac user, using the excellent TunnelBlick OpenVPN client, this is easy for me, as they helpfully provide a вЂRoute all IPv4 traffic through the VPNвЂ™ tick box. As access is not permitted outside of the office though, this request will eventually fail. Unfortunately, this breaks the configuration above because as the hostname of the resource can be looked up on the open internet, the client thinks it should be able to access it outside of the VPN.

These systems are by necessity available on the public internet, but we generally use firewalls to only permit access from the office. There is one interesting exception to this however, and that is systems on public cloud providers like AmazonвЂ™s AWS. We know this isnвЂ™t the most secure option, but it works for us for the moment. This is a really great way of reducing traffic through the VPN to include only access to essential resources. If I try to access something like, that isnвЂ™t on the open internet, access takes place through the VPN.

If it canвЂ™t, it then tries inside the VPN tunnel.ДЇor example, with the VPN connected, if I try to go to, access occurs out side of the VPN as the resource is on the open internet. In general itвЂ™s great, however when working away from the office, itвЂ™s configured such that any request for a resource first checks outside of the firewall to see if it can access it.

We use the open source OpenVPN for our office VPN. This is a really quick one, as we use this trick a lot when working remotely, but we always have to scrabble around to find the info!
