Hi to all!
![7858 Full Network Diagram.jpg](/legacyfs/online/legacy/2/2/8/140822-7858%20Full%20Network%20Diagram.jpg)
I'm not good in Cisco networking, that is why i posted this question here. To get some idea what is going-on on our office network. Because the ISP is not willing to help to solve the problem. Let me tell a brief overview of our network. We have a vpn setup in our office, the setup is done by our ISP and they said this is a webvpn. I'm not so sure... I just knew its a vpn.. . Since when I join the company the vpn between the head office and the site office is working fine and there is no changes made on the setup of the routers. Then suddenly is not communicating... Our router Cisco 1800 from head office can ping the route Cisco 1900 on the site office, but the site office cannot ping.
If anyone had experienced this before please help me. Why the router of head office can ping the site office router, and the site cannot? What is causing this situation?
