Hello there, this is Yuron. This time, I’m going to explain some points to note when using the ER605 as an OpenVPN client, since I ran into a problem when connecting to a Pritunl OpenVPN server built on AWS using the TP-Link ER605 as an OpenVPN client. TOC Tips for setting .ovpn on ER605 Tips for fixing .ovpn Tips if you have trouble connecting to OpenVPN Tips for setting .ovpn on ER605 The OpenVPN version that can be used with the ER605 is 2.4 or earlier. In other words, the TP-Link ER605 cannot interpret the OpenVPN v2.5 syntax used in the latest version of Pritunl, v.1.20 and later, and processing stops midway.
