Hello, I have been upgrading a number of Mikrotik Hex routers to 7.x in order to allow for OpenVPN UDP connections to a CHR. This has worked for several but I am now encountering some units that just don’t seem to have the UDP option when creating the connection. it’s just NOT there…? They appear identical in hardware specs running the same firmware and release. Am I missing something? Here is the info… Router #1 interfaces-> Add->OVPN client has UDP as an option and router #2 does not.
