I'm hoping someone will be able to help me figure out an issue that I'm having. I'm sure it's something simple that I'm missing. What I have is a site to site vpn tunnel between a Cisco 2801 and a Cisco 1841 router. The tunnel itself is up and running without a problem. My issue is that I am unable to get traffic across the tunnel between the two sites. For instance, I try to ping a computer in Site B from Site A and I get no response. Try to run a tracert in Windows and it drops off at the router and goes no where.
Any ideas on what I may be missing? I know the configuration information will help so let me know which pieces you'll need to see for that.
