As we can see from logging results from the firewall between the VLANS there is traffic between servers using port 21571. I found that this is caused by NLSLRUP.NLM from Netware Product Usage.

So far no problem, this is normal traffic. There is only one problem, the traffic is from serveral servers to iSCSI ip addresses from 3 servers using iSCSI. I already disabled SLP (and NCP) at the iSCSI ip addresses, without solving this.

Trough iManager / Netware Product Usage, i can see that the servers a advertising with SLP. So maybe there is some reference to the iSCSI adresses that needs to be deleted.

Anyone an idea?

Using Netware 6.5 SP6

Thanks in advance,
