There is a CISCO firewall in the branch which has 117.x.x.x as gateway and users are connected to this router obtaining IP address through DHCP.The router is connected to internet through an ISP-1 which connects to Head Office. There is an alternate ISP-2 whose gateway is added in the router/firewall of the branch. When ISP-1 is down users connect through ISP-2 (say 10.x.x.x) by using the gateway of ISP-2 as proxy in the browser. ISP-1 connects to internet and intranet through a proxy script that is mentioned under the "use automatic configuration script". Now if a computer from the internet wants to connect to any of the computer of the branch office by using Team Viewer, then is it possible to get a log to get to know who has tried to connect to the computer of the branch from the internet. PRTG is installed in H.O and PRTG can view whether the internet connection at Branch Office is down or up. Is there any software/utility like PRTG or MRTG which can get the information or can it be known from the logs of the firewall whether any body has accessed the computer in branch office from the internet through Team Viewer
