Unable to Use Telnet Because Firewall is Blocking "System"

RalphMalph

I am trying to use a telnet connection between a custom app and a terminal emulator and Sophos Firewall blocks the connection saying invalid checksum for "system".  I have no idea how to add a checksum for "system".  What is this trying to tell me?

    Hello RalphMalph,

    haven't seen something like this - system is the kernel and doesn't have a checksum. Could you post the log record's details (and are there corresponding entries in the Events subtree)? If this is on Win7, are you using Interactive mode?
