I have a Cisco ASA that I have VPN tunnels to connect my internal Windows network. I ran into some trouble logging into my domain so I unblocked all the ports on that internal interface. On a previous question posted here, the general consensus was that I should be blocking ports on my inside interface but my question is: what ports should I unblock? I've tried unblocking ports 88, 139, 135, 389, and 445 and Windows logins still give me problems. Is there some MS documentation somewhere that tells me what I need to unblock to allow Windows logins and other things?

Managed hosting firewall vs managing own firewall

I posted on stackoverflow as to the overall benefits of managed hosting vs non-managed hosting. The more I think about it, it seems to boil down to one question: should I use a managed host because they take care of the firewall, or would I be okay managing my own, software firewall?
