Hi Shannon, if you write a filter, use the type "IP filter" with protocol=17 (UDP) for source and dest port=137 protocol=17 (UDP) for source and dest port=138 protocol=6 (TCP) for source and dest port=139 But be warned that this will not stop all traffic from Win machines. Further candidates for filtering may be port 135 for RPC and port 53 for WINS over DNS. Especially during the boot phase I still observe dialouts even with the common 137-139 filters. But then again, who cares? Best regards, Wolfgang >From: Shannon Price <shannon at starnetusa.net> > >Trying to block all UDP (ports 137,138 and 139) traffic via a filter on the >Ethernet.
