Hello, 
 
Can anyone give me an example config on how to PAT based on destination address? 
 
Site A: 
Cisco C2800 ISR 
LAN: 10.10.10.0/24 
Public address: 1.1.1.1 
VPN Peer 2.2.2.2 
 
Site B: 
Cisco Concentrator 3005 
LAN: 172.22.22.0/24 
Public address: 2.2.2.2 
VPN Peer 1.1.1.1 
 
 
At site (A) I have a Cisco 2800 router with a VPN connection to site B. 
On sites A's router, I need to configure PAT only when destined for host 172.22.22.22 that is on the other side of the VPN tunnel. All traffic from network 10.10.10.0/24 will be PATed to 172.21.21.21. 
All other traffic PAT's the same out their respective interface. 
 
 
Any help would be much appreciated. 
 
Thanks!

CIsco 2800 Router NAT/PAT based on destination address

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
