IP Filter Function
This function identifies the source IP address of accessing devices, thus preventing unauthorized access.
Specifying the IP address of the other device restricts access by the other device using Ethernet port (CH1). Restricting
access to communications routes using Ethernet can provide optimal security for the network environment.
For security for Ethernet port (CH2), use the Windows standard functions or security software.
Precautions
• If a proxy server exists on the LAN circuit, block the IP address of the proxy server. If this is not block, access from
computers that can access the proxy server will not be prevented.
• Do not use the firewall function via standard operation of VxWorks when using the IP filter function. If the firewall function is
used, the IP filter function may not run normally.
