We have a customer that recently changed IT Vedors and came to us. We needed to change the ISP and need to make changes in their Firewall. I went out on site and wasn able to get into the Routers and I contacted the previos company but they wouldn release that information. So we had to reset the devices and set everything back up. Everything works great except before they had an IPSEC VPN Tunnel between the 2 buildings. Both Buildings have WRVS4400N Routers and I have setup a VPN IPSEC Tunnel on both sides. I have named them the same and the summary says that both are up. But when I try to go from one side to the other I am unable to Ping or resolve anything. I will put all the information that I may think is relavent to this problem and hope someone can help me. I called Cisco but they said they are out of warranty and will not be able to help. Cisco directed me here.
For security purposes the IPs are not exactly what is being posted but I have checked them 10 times and they match what the remote side says. Again both say they are up but I am unable to ping or see devices from the tunnel. Please help.
Thanks in advance
