I want to do the following: (relevant config first)

-------------------------------------

router a:

fastethernet 0/0
(local)
ip address 192.168.0.1 255.255.255.0
ip nat inside


fastethernet 0/1
(wan)
ip address 213.1.1.2 255.255.255.192
ip nat outside


interface Tunnel1
ip address 10.200.1.1 255.255.255.252
tunnel source 213.1.1.2
tunnel destination 213.2.2.2


ip nat pool natpool 213.1.1.2 213.1.1.2 prefix-length 24
ip nat inside source list 150 pool natpool overload
ip route 0.0.0.0 0.0.0.0 213.1.1.1
ip route 192.168.1.0 255.255.255.0 10.200.1.2
access-list 150 permit ip 102.168.0.0 0.0.0.255 any


---------------------------------------------------------------


router b:

fastethernet 0/0
(local)
ip address 192.168.1.1 255.255.255.0
ip nat inside


fastethernet 0/1
(wan)
ip address 213.2.2.2 255.255.255.192
ip nat outside


interface Tunnel1
ip address 10.200.1.2 255.255.255.252
tunnel source 213.2.2.2
tunnel destination 213.1.1.2


ip nat pool natpool 213.2.2.2 213.2.2.2 prefix-length 24
ip nat inside source list 150 pool natpool overload
ip route 0.0.0.0 0.0.0.0 213.2.2.1
ip route 192.168.0.0 255.255.255.0 10.200.1.1
access-list 150 permit ip 102.168.1.0 0.0.0.255 any

--------------------------------------------------------------

I want traffic from a certain PC behind router b (192.168.1.2) in and out using router a's wan connection
(pc - router b - tunnel 1- router a - nat - internet - nat - router a - tunnel 1 - router b - pc)
How do I have to change the configs to do this? (please include the changed lines)

Thanks in advance! :)
 
If you only want traffic from a certain IP to take that path then you need to use Policy-Based Routing.
 
Yes.. But my attempt did not work.. I created a route-map that match the host ip (acl) and st the next hop ip to the other side of the tunnel.

I also added the host to the nat ACL on the router that I want to NAT the traffic for the host.. The routes are correct (the host can ping the router (all interfaces) on the other side of the tunnel)

Do any of you have an example of how you would do this?
