Hi guys,

I really dont get it. Depends where i ping from and the message for the ping that i get, the packet go for one route or another, this is right or i did something wrong?

NAT inside & Route map config

```
ip nat inside source route-map ISP1 interface Ethernet0/1 overload
ip nat inside source route-map ISP2 interface Ethernet0/2 overload
ip route 0.0.0.0 0.0.0.0 192.168.12.2
ip route 0.0.0.0 0.0.0.0 192.168.14.2
!
access-list 1 permit 192.168.10.0 0.0.0.255
!
route-map ISP2 permit 10
 match ip address 1
 set interface Ethernet0/2
!
route-map ISP1 permit 10
 match ip address 1
 set interface Ethernet0/1

```

ip route output

```
NAT#sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
       + - replicated route, % - next hop override

Gateway of last resort is 192.168.14.2 to network 0.0.0.0

S* 0.0.0.0/0 [1/0] via 192.168.14.2
                [1/0] via 192.168.12.2
      192.168.10.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.168.10.0/24 is directly connected, Ethernet0/0
L 192.168.10.2/32 is directly connected, Ethernet0/0
      192.168.12.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.168.12.0/24 is directly connected, Ethernet0/1
L 192.168.12.1/32 is directly connected, Ethernet0/1
      192.168.14.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.168.14.0/24 is directly connected, Ethernet0/2
L 192.168.14.1/32 is directly connected, Ethernet0/2

```

Thanks in advance.
