Dear Kaulquappe In our project we are supposed to use LAN as the backbone for SCADA / Field communication. For the sake of network security we have to put a Cisco firewall in control center as an interface between LAN and servers. At field side we have several standard S7-400 AS which will communicate through their CP443 via IEC60870-5-104 protocol. Please have a look at the configured network attached. IPs for S7-Station, Firewall, Servers, and Notebook are also illustrated. The issue is that communication between servers and test notebook is OK but S7 stations could not even be pinged by servers. Gateways on S7(CP443) and notebook are defined similar to that of firewall's IP. S7 to server communication is activated as soon as the firewall is bypassed. That means S7 could not communicate through firewall as its gateway. I wonder if some other parameters should be set in HW config.
