Ubiquiti Edgerouter VPN Configuration

I typically encounter situations where I need to come up with a solution. Sometimes it is a temporary solution while we wait for the ‘proper one to get deployed’ other times, its more of a proof of concept to see if the client will actually use it.

A great example is when I installed a Ubiquiti router for a client at a remote office. We had a discussion afterwards about support and monitoring. Of course, I bring that up since a majority of my work involves troubleshooting.

I respected the client’s honesty when he bluntly said “We have thought of it, but not had any time to follow-up as of yet”.  I totally understand and appreciate what he means. He then added that they are currently using the Ubiquiti cloud network management platform. After a quick chat we both realized that there are some blind spots in their monitoring and inability to easily connect to the office locally.

His face lit up when I suggested we set up a test VPN, so we can VPN into the office router and then have full access to all the local hosts and resources. He was concerned that this was going to be complicated and wondered how much this was going to cost.

When I explained that all their routers support various VPN access options and that I have done this before, he gave me the nod to proceed.  An hour later, he and the support team where VPN’ed in and happy as can be. I ended up using a LT2P configuration since it was the easiest and most compatible. i figure if he likes, and uses the VPN solution, we can change it to Openvpn or Wireguard later.
