Hello Matrikon,
I wanted to ask you about the possibilities of the tunneller.
We are evaluating an architecture where 3 tunnellers are needed with the following architecture
Tun1 -> Tun2 -> Tun3
Between each Tunneller there is a firewall. The query is, Can Tun3 read the data from the opc servers that are in Tun1 through Tun2?
Thank you

Hi Charles,
You would need a "bridge" in between. Tunneller Server-Side Component (SSC) cannot connect to another Client-Side Component (CSC) without this. MatrikonOPC Funnel will work perfectly here as follows:

OPC Client>TunnellerCSC>>TunnellerSSC>Funnel>TunnellerCSC>>TunnellerSSC>OPC Server

There are also other solutions for DMZ situations depending on what you are trying to do and what the security constraints are.
