This is the configuration that works, i hope that it can help someone else.
Here is a redirection using protocols:
ip access-list extended pbr_acl
permit tcp 192.168.0.0 0.0.255.255 any eq pop3
permit tcp 192.168.0.0 0.0.255.255 any eq smtp
permit tcp 192.168.0.0 0.0.255.255 any eq 465
permit tcp 192.168.0.0 0.0.255.255 any eq 993
permit tcp 192.168.0.0 0.0.255.255 any eq 995
permit tcp 192.168.0.0 0.0.255.255 any eq 587
permit tcp 192.168.0.0 0.0.255.255 any eq 143
route-map pbr_navigation_dial permit 10
match ip address pbr_acl
set interface Dialer0
And here the configuration using ips:
ip nat inside source list acl_dial interface Dialer0 overload
ip access-list extended acl_dial
permit ip 192.168.0.0 0.0.255.255 host x.x.x.1
permit ip 192.168.0.0 0.0.255.255 host x.x.x.2
ip route x.x.x.1 255.255.255.255 Dialer0
ip route x.x.x.2 255.255.255.255 Dialer0
Add a more specific route to the IP of the cloud service via the ftth interface.
So - ip route ip.of.cloud.svc 255.255.255.255 dialer0
should send traffic via the dial0 interface.
