access-list 101 permit ip any any
access-list 102 permit ip any any
route-map PBR1 permit 10
match ip address 101
set interface fa0/3
route-map PBR2 permit 10
match ip address 102
set interface fa0/4
int fa0/1
ip policy route-map PBR1
int fa0/2
ip policy route-map PBR2
Be aware that this will send ALL traffic to any destination received on fa0/1 to fa0/3 and ditto for fa0/2 / fa0/4. If for example you only wanted to send internet traffic then you need to use deny statements in the acls for the other networks eg.
lets suppose that there is a network 192.168.5.0/24 that is reachable via fa0/2. Now there is a client A that is connected to a subnet reachable via fa0/1 on the router. With the above PBR config when client A sends a packet to a device on 192.168.5.x it would actually get forwarded out of fa0/3 interface. So you would need to modify your PBR config ie.
access-list 101 deny ip any 192.168.5.0 0.0.0.255
access-list 101 permit ip any any
then any traffic received on fa0/1 with a destination IP of 192.168.5.x would not be policy routed but routed via the routing table.
