i'm trying to configure an IPSec VPN tunnel between 2 Cisco routers connected to internet via ATM interface, my router is a 1841 with network address 10.200.36.0, the remote router is a Cisco 877 with network address 192.168.9.0.
I tryied to follow some tutorials, without success because i still can't ping any IP address on the remote network and also the VPN tunnel is not up!
May you please help me giving a configuration template, or maybe let me know how to configure it step by step on mine and remote router?
so you are receiving traffic through the tunnel, but you don't send anything (last two lines). A typical problem is misconfigured NAT. Make sure that the traffic from your network to the other network is not NATted.
