NAT with dual wan ISP connections

[saikrishna]

Hi,

We are using two WAN ISP connections with Public addresses, and they have given free 5 IP's for each WAN.
We have given VIP, NAT and Rules with 1 WAN ISP IP's, Everything is working fine with those IP's
The problem exists here is when we are trying to group the both gateways for member down or failover, and adding that gateway to lan rules then those servers with NAT is not working.

Can any one suggest me the solution. Please revert back as soon as possible. Quick response is greatly appreciated.

Thanks.
