AC500 over GSM
Hi
I have an issue with connection to AC500 (PM573) over 3G router.
My config looks as below :
(Automation Builder 2.1) PC -> LAN (-> GRE TUNNEL->)3G operator router->AC500.
I can ping AC500 but nothing else.
Automation Builder cannot conect to PLC, and also can not search it by "IP tool".
I have long Ping time -around 300-600ms and as i have observed - when Automation Builder/CoDeSys tries to connect - first it sends the ping and waits for the respond.
If response from PLC comes quickly (LAN connection) then the connection is estabilished.
But in my case, it takes more than 300ms and before PLC reponds - CoDeSys shows the information, which says that there is no PLC connected.
Have someone any ideas ?

Greetings,
For wide area connections, you have to be sure about out 3G Router settings.
As far as I know, your 3G Router has to support VPN Point-to-Point Connection.
If it does not, or it blocks some kind of protocols, you can ping remote device but you can not connect through Automation Builder.
Hope it helps.
