My company is about to move from one location to another. We are not doing it all at once however. All of our administration is moving in the first phase, and the rest are to follow in 2-4 weeks. What this means is that I need to support both locations for near a month. I plan on doing this by creating a site-to-site VPN. The VPN is not currently my problem. At Site2 (the new location) I have a Cisco 2620 with a WIC-1DSU-T1 card, connected to a full T1. The Serial0/0 Interface is completely up, and I can ping out anywhere, including to my current network at Site1. From Site1, I can ping both the external Serial0/0 interface and the internet FastEthernet0/0 interface of the Cisco 2620 router at Site2. However, I am unable to ping anything on the internal network, from Site1. There is currently onle 1 device on the internal network at Site2, and its IP address is one that was supplied by my ISP. If I telnet from Site1 to the router at Site2, I can ping the IP address of the host in the inside of the network, so I know that it is online. The question is, why can’t I ping from Site1 to the inside of Site2? Is it a routing problem? If I do a tracert, it makes it all the way to the outside interface Serial0/0 of the Cisco2620.
