Unable to Use Telnet Because Firewall is Blocking "System"

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,

    I had to do a search of the entire Windows directory

    normally SEC's Event viewer should enable you to amend the policies as required (but of course if you use it the client should be compliant with the policy on the server - otherwise you'd overwrite the local changes).
