Trying to communicate (from Europe) with/to a unit located in china, the communication seems blocked/stopped.
The edge gateway is installed in a linux environment and was possible to link to my Automation server account using the "Automation service tool". However it seems the unit cannot communicate with the Automation server (a Network scan will give the message "Gateway not connected").
(I have tested the eq. setup with units locally which works.)
Anyone having experience situation similar to this and if its possible to make this work? Will a VPN be needed possibly? Other tips?

I think I understand my problem. They are most probably related to configuration of the network. When I use DHCP for the unit to my router it all works. However when using static IP I have not managed to reach functioning state.
Trying to replicate the situation on my desk. Having a static IP on the "debian host" and a connection to my computer which then routes traffic on to internet. I have entered settings for gateway and netmask.
I can ping from my "debian plc host" to internet and also do "curl google.com" so traffic seems to find its way through and back, still "Automation server" will not find the gateway.
Any hints how a manual configuration should be done? Is it possibly a "firewall" issue of my "normal router"? Thanks for any help!

We have tested this and it had worked at that time with China.
which device is it? Anything special?
Gateway and runtime (Control for linux SL) on a debian linux.
Thanks for your check. Good to know. I will probably travel there in about a months time so that will give me better possibility for further testing.
(on a side note, I dont get mail-updates on forum-subscriptions, need to check the topics manually)
