Hi,

In my case.
1. yes
2. about 10
3. because i need outside access to my machine.

My problem, that i think is very similar to other related here (and i'm
sorry for this cross-posting) is that i have a PDC on the same server of the
ADSL connection. People edits, for example, files in the apache directory
through samba and i want that a client access outside my office. But, if i
have a strong firewall in this machine, the win2k workstations doesn't find
the domain controller. So i don't have any rules configured, just enabled
all to anywhere from anywhere.

I allowed 'netbios-ns,netbios-dgm,netbios-ssn,isakmp,wins,microsoft-ds' for
the LAN but still not worked... I think i'll have to open more ports.

So, any guess?

Luciano
