There are three vlans on the core switch, VLAN 15,16,17
The traffic going from VLAN 15 into VLAN 16/17 should be NAT'ed. So VLAN 15 has ip nat inside and VLAN16/17 has ip nat outside. NAT is working fine from VLAN15 into VLAN16 with 'ip nat inside source static x x'.
How can I define the NAT'ed ip list for VLAN17 because I want to NAT the same source IP to a different IP when going into each of the other VLANs. I believe 'ip nat inside source' will not allow the same source ip to be natt'ed to different ip based on the destination VLAN.
How can this be achieved.
Okay, try this -
vlan 15 = 192.168.5.0/24
vlan 16 = 192.168.10.0/24
vlan 17 = 192.168.11.0/24
access-list 101 permit ip 192.168.5.0 0.0.0.255 192.168.10.0 0.0.0.255
access-list 102 permit ip 192.168.5.0 0.0.0.255
ip nat inside source static 192.168.5.10 172.22.1.1 route-map PNAT1 extendable
ip nat inside source static 192.168.5.10 172.22.1.2 route-map PNAT2 extendable
route-map PNAT1 permit 10
match ip address 101
route-map PNAT2 permit 10
match ip address 102
Note i have used 172.22.1.x addresses for NAT, obviously you need to substitute with what you have.
