I am getting ready to to try to do a Remote Network Scan. I have 25 remote offices that are connected to the main servers here only via terminal services. No VPN. To do a network scan I know I need to open ports 7,135,445,1085 on the firewall. However how am I going to scan the network behind the firewall? If I scan the static IP of the firewall that isn't going to work correct? (Public IP and workstations are 192.X.X.X) I do have file servers at each of this locations that I can log into via terminal services. Can I log into them, then log into SD as admin and do the scan? I assume not cause it has to be local to the SD server correct?
Please advise and thank you for your time in advance.
