“10.0.0.10” is your i5?
And 188.8.131.52 is outside of your network?
Well, you could block port 445 on your i5, or you could block incoming traffic on 445 at your network firewall. There is a worm that is known to use 445. But, it’s going to be looking at your “windows” netserver on the i5.
Its probably not going to bother the QSYS lib, but that doesn’t mean that you couldn’t have something turn up in a share in the IFS.
Seems like your network security people should be helping you with answers to possible intrusions.
Port 445 is the standard port for cifs (used by Microsoft for SMB over TCP/IP). This is the port that NetServer listens on. End your NetServer server if you don’t want it listening.
Usually, that’s not an option. NetServer has become too important not to run it or to block port 445 at your i5. What most people do is use a firewall to block access to such ports from the outside.
If you have a firewall for your network, it’s misconfigured or it’s compromised.
