Answer 1

PPPOE is not SECURE! ----plan and simple.



BUT that's not you problem



What you need to do it set up Active Directory (Linux LDAP) in windows server. With that you can give users to only limited rights on what they can do and cannot do.



If you are using a windows xp type os, its a BAD IDEA, reason is that it does not have the restriction that a server OS has and it is a big security risk. (I use linux, I use Mandriva Corp Server 4)



If you use ANYTHING from Microshaft, you WILL need to buy or update/antivirus/antispam and other stuff needed for a microshaft system. Linux does not need all of that extra cost to keep it running.



The part of using 2 NIC's is a good idea for a pc/server as a firewall in the network.



Oh buy some O'Reilly books

Answer 2

Jeez, and you are the IT Admin ?



One reason why you have 2 LAN cards is because whoever set this up must be thinking of using ISA, so one card will face inward and one card will face outward to create a firewall scenario.



You need to check if you have ISA installed (not saying what server you are running on really no help at all), if yes, then you can set the policy from ISA server to control the traffics, but how users access the internet is another matter, you really should seek professional advice from a cert'd company or you will be hack in the long run.
