Minimum ports required to traverse segmented network Win7 Client and SBS2011 communication
Posted on 2012-08-23
We are using network segmentation across vlans as a security control. I have a firewall between the vlans but its completely open right now. I'd like to configure the firewall to drop all unsolicited traffic between the two networks but I can't seem to find a good resource detailing the ports used to communicate between Win7 and SBS2011 Standard for default roles (exchange, sharepoint, active directory, etc). If anyone has a nice spreadsheet that has this information at a glance it would be greatly appreciated!
