Need Help on Dual NAT(Double NAT)

[girish]

Hi Team, I need your help for  Dual NAT for requirements.  How to proceed with both Source NAT dynamic and Destination(one-one) NAT ..?

Before Hitting fw

Source IP :2.2.2.0/24 Destination: 1.1.1.1

After hitting fw

Source IP : 3.3.3.3/27 (source NAT dynamic) Destination: 11.11.11.1 (DST NAT static )

SNAT w/ specific IP other than the interface IP is done by ippool. DNAT is always done by VIP. You need to configure both and put them into one policy. You can find some examples at least separately when you search both through cookbooks, online help, or just internet.

Hi Girish,

Did you manage to get anywhere with this? I have a similar requirement and can't seem to find anything to tie both source and destination NAT together.

Thanks,

Neil
