Current setup and Equipment
Cisco Internet Router
It’s that simple.
Currently the SBS server only has Exchange Server 2003 installed but if you know SBS, it comes with ISA 2000, which I want to implement. And of course its the domain controller for out internal domain.
What I want to achieve at the end of all this from an external services point of view is, OWA access, OMA access, Onsite SMTP server (is currently functioning) and VPN access. From an internal point of view I need the internet filtering and security capabilities of ISA.
All this now leads to the main question. What network setup would best suit my needs? Security is very important although these services are required.
Just to let you know some of the things I am currently pondering, I have thought about a DMZ, breaking SBS2k3 so that I can split it onto separate hardware ($$) or putting two network cards into the SBS domain controller and installing ISA in integrated mode and then using private IP's in the DMZ etc etc
