I have the following rules...
1 deny 0.0.0.0/0 0.0.0.0/0 tcp dst eq 137
2 deny 0.0.0.0/0 0.0.0.0/0 tcp dst eq 138
3 deny 0.0.0.0/0 0.0.0.0/0 tcp dst eq 139
for a filter called ether.in
and
1 deny 0.0.0.0/0 0.0.0.0/0 tcp dst eq 137
2 deny 0.0.0.0/0 0.0.0.0/0 tcp dst eq 138
3 deny 0.0.0.0/0 0.0.0.0/0 tcp dst eq 139
And then I have
set ether0 ifilter ether.in and hey presto
the Portmaster stops responding..
I try it reverse set ether0 ofilter ether.out
and alls ok for a bit then it stops.
All I want to do is block ports 137 and 138
and 139 from users on dialin ports and from
the ethernet.
And I think it is something obvious for people
who have done it before.
Many Thanks
Martin
