Ubiquiti EdgeRouter 4
I need to set up a site-to-site VPN to another company for my business. At the moment we only have a CTS FTTH gateway VRG5-31412 from Sunrise. Is it possible to set up such a VPN using the Ubiquiti EdgeRouter 4 and use my current router as a Wifi access point? Or what other components are needed to set up a site-to-site VPN and still have wifi in the shop?
