WAN load balancing

Question

Hello
 I have the following issue with a Cisco 2811 router. I have two WAN connection ( fiber and ADSL ) and I want to make WAN load balancing
so I add two route : 0.0.0.0 0.0.0.0 dialer1 and 0.0.0.0 0.0.0.0 fa1 the problem is with fiber connection (fa1) in this configuration I can't ping WAN 
from outside or use NAT on this connection. If I change default route's like this it's working but is not WAN load balancing : 0.0.0.0 0.0.0.0 dialer 150
0.0.0.0 0.0.0.0 fa1. Any idea.

Hi Richard
I come back with more details:
First I try to setup router with WAN failover like this:
route-map SDM_RMAP_1 permit 1
 match ip address 101
 match interface FastEthernet0/0
route-map SDM_RMAP_2 permit 1
 match ip address 102
 match interface Dialer1
access-list 101 permit ip 10.0.0.0 0.255.255.255 any
access-list 101 permit ip 172.26.60.0 0.0.0.255 any
access-list 102 permit ip 10.0.0.0 0.255.255.255 any
dialer-list 102 protocol ip permit
ip nat inside source route-map SDM_RMAP_1 interface FastEthernet0/0 overload
ip nat inside source route-map SDM_RMAP_2 interface Dialer1 overload
ip nat inside source static tcp 10.0.0.1 25 x.x.x.x 25 route-map SDM_RMAP_1 extendable
ip route 0.0.0.0 0.0.0.0 x.x.x.x 150
ip route 0.0.0.0 0.0.0.0 y.y.y.y track 1 
interface FastEthernet0/0
 ip address x.x.x.x 
 ip nat outside
 ip virtual-reassembly in
 duplex auto
 speed auto
 no cdp enable
 crypto map SDM_CMAP_1
interface FastEthernet0/1
 no ip address
 ip mtu 1492
 ip nat outside
 ip virtual-reassembly in
 duplex auto
 speed auto
 pppoe enable group global
 pppoe-client dial-pool-number 1
interface Dialer1
 ip address negotiated
 ip mtu 1492
 ip nat outside
 ip virtual-reassembly in
 encapsulation ppp
 dialer pool 1
 dialer-group 1
 ppp authentication chap pap callin
 ppp chap hostname ...............
 ppp chap password 7 010109085702121F33434A0014524343
 ppp pap sent-username .......... password 7 0614002D40471D091718160201537E7A
 no cdp enable
 crypto map SDM_CMAP_1
track timer interface 5
track 1 ip sla 1 reachability
 delay down 15 up 10
ip sla 1
 icmp-echo a.b.c.d source-interface y.y.y.y
 timeout 5000
 threshold 40
 frequency 6000
ip sla schedule 1 life forever start-time now
And I want to achive the following results:
All computers from LAN use for internet connection y.y.y.y and if this failed use x.x.x.x and when come back y.y.y.y use this connection.
And I have one server with few services ( DNS, WWW, MAIL...)  which must use just x.x.x.x connection if this failed dosen't matter if this services not working.
But with this configuration one thing not working i can't access from outside Mail server , DNS, WWW  with x.x.x.x connection ( IP ) if I change default route like :
ip route 0.0.0.0 0.0.0.0 x.x.x.x  track 1
ip route 0.0.0.0 0.0.0.0 y.y.y.y  150
it's working
