HI experts,
i have a consideration creating a some load balance through ASA using NAT features. but i am getting stuck in one place.
(outside1) WAN1 --------- ------ VLAN1 (inside)
public IP range | |
ASA
| |
<<<< ADSL router ------------- (outside2) WAN2 --------- ------ VLAN2 (inside)
public IP range private address range
i configured wan 1 as a default route with lower metric and Wan 2 as a default route with higher metric. so VLAN1 and VLAN2 users can access internet using wan1 by default route. ADSL router doing his nat and internet part properly. i wanted to send vlan 2 traffic through wan2. for that requirement i created a static nat from vlan2 all IPs to wan2 IPs (i can make many static nats because its private address range) interfaces and network address ranges. but when i run packet tracer ASA using wan1 as a outside interface to vlan2 traffic.
i have seen routing is happening before nat process. so i identified this problem occurs because of that. i have done this successfully in asa5510 and its not working on 5515 with 9.1(3) OS version.
any ideas which i can drive wrong path?
Thanks in advance for any idea
PS: unfortunately i am not able to post configuration or ip addressing due to security policies. your ideas will be gold point to me. :)

It's tough troubleshooting without seeing the config, but did you by change accidently enabled 'route-lookup' on the static nat rule?

Hi Niels,
thanks for reply..
Actually i have not used 'route-lookup' command on nat commands.
i guess this is a OS bug according to http://packetpushers.net/understanding-when-a-cisco-asa-nat-rule-can-override-the-asa-routing-table/ and waiting for TAC support.
thanks
