We are trying to setup remote PLC's (Compactlogix) to talk through the ICX35. I was able to configure the ICX35 and get it on the cellular network, but not we want to connect the PLC's together and to our SCADA machine. The customer does not want to pay the ProSoft connect annual fee, so we are trying to configure firewall routers (either Sonicwall or FortiNet) to achieve this. What we have done in the past is used an ISP modem in bridge mode, and then used the firewall to create the VPN between the sites. I can't find anything in the ICX35 that would enable a bridge mode, so I was wondering if anyone has successfully done what I am trying do to.
