It looks like they added another new scanning computer. They were using
jsl5 (129.57.71.15) which I blocked at the opsnet router interface. We
have asked them not to scan the opsnet at all but something gets
misconfigured/reconfigured and the next thing you know they are scanning
it again. I guess I will have to block this machine also.
