I'm trying to add some devices in RME that are physically located in china and behind the firewall. ping response is aboit 260 msec. I have opened up the necessary firewall for telnet but the config fetch/archive still fails with the telnet timeout. I have increased the timeout value to 180 sec but still no avail. What is the best way to manage the device that have high latency? How can I successfully manage them in RME?
