I need to tighten up my networks firewall policies. I was hoping someone could post the recommended ports that need opened for a secure SMB.
I have only 4 ports I can think of that I would absolutely need to have open. The internet (HTTP and HTTPS) and Exchange 2010 (Incoming and Outgoing SMTP SSL)
I'm sure there are allot more ports I'd like to use, such as Remote Desktop, VPN, POP3, Windows Update and ActiveSync.
Does anyone have a preconfigured list of ports to open for the average small business?
