Hi all,
I have a problem with wonderware 9.5 comms over VPN..
We have a set-up where we connect Scada and two PLC'S through VPN connection.
I have found that I can ping the PLC 's from Scada Station but neither its communicates with Rslinx nor with wonderware
Following are the error showing in RS Linx Event Log
07/24/13 22:51:39 192.168.1.10 Unable to establish TCP connection to the Ethernet Interface
07/24/13 22:51:39 192.168.1.10 [10060] Connection timed out

07/24/13 22:52:31 192.168.1.10 Unable to establish TCP connection to the Ethernet Interface
Our Scada System in wonderware Intouch 9.5 and PLC'S are compact Logix L32E
We are using Viola m2m Gateway (Scada) and 2 Viola Arctic Router(PLC's)
Is there any port forwarding required?
Is there any firewall issue?
Regards
Joseph
