We have replaced our PIX with ASA 5510 and are running, ASA Version 8.3(1) & asdm-631.bin.
We have 1 ASA and 2 WAN's. So I have configured Failover, so that if primary WAN fails secondary will be active, which works fine. Only problem is NAT rules. So, if I have 2 set of NAT rules 1 for WAN1 & 1 for WAN2, only 1st NAT rule corresponding to the active WAN circuit in the NAT list works and none of other rules work.
I have copied some nat config below (I have not got WAN2 nat rules in there. If I have them, then problem will reoccur) and have also attached ASDM screeshot of NAT rules. Lastly, just so that you have better idea, what I want to achieve is Static NAT to work in case of WAN failover. Do I neeed Twice NAT and hopw to configure?
