Francis,
Thanks for your guide. I am not familer with firewall setting.
So I asking you more question here.If my server is only used
as POP3,SMTP,WWW server, and additionally terminal service.
I plan to set up Input Filter as following:
protocol: TCP(destination port: 25,110,80,3389)
TCP(established)
UDP(source port : 42)for dns
Is that OK? and NetBIOS will not exist,right?
