F5 Link Controller above existing NAT Firewall

Hi Dev. :)

 

Before F5 Link Controller implementation, i need to ask something regarding design

 

My design requirement are to optimize 2 link by ISP (internet), for incoming critical application at Data Center (Web Server, Email and FTP) and outgoing Internet Service for internal user

 

The deployment must be less effort to reconfigure existing Firewall, existing firewall now is NAT (SNAT/DNAT) device and access control, that handle IP public address from 2 ISP.

 

My question are, how F5 LC handle this ?

 

Can it deploy with transparant ? I mean we dont want migrate our NAT config into F5 LC Appliance.

 

Please kindly help us with solution. :)

 

regards
