I have router DSL 877 and uc520 connecting to each other, and I have PC outside installed on it Cisco VPN client and Cisco ip communicator, I want to make IP communicator working with uc520, the problem is I have already configure the VPN on router and it is working, but I can not ping the uc520,
I have attached the Visio layout how is the connection, and the configuration.
As per your topology, your voice subnet (10.1.1.0/24) is currently the same as your VPN IP pool subnet (10.1.1.x) . You would need to change the VPN IP Pool subnet to a unique subnet so routing will work.
Further to that, you would also need to change the following ACL 1 assigned to your NAT:
ip nat inside source list 1 interface Dialer0 overload
I already replaced "ip nat inside source list 1 interface Dialer0 overload" to "ip nat inside source list 150interface Dialer0 overload" and I add one command on router 877 for new subnet "ip route 172.16.1.0 0.0.0.255 10.10.10.10" and on uc520 there is ip defualt route "0.0.0.0 0.0.0.0 10.10.10.1"
