The source address translation would occur between the BIG-IP and the destination server(s). You can use SNAT automap on the VIP to allow LTM to dynamically select the (or one of) the floating IP addresses on the egress VLAN. Or if you want to specify a source IP address that LTM should use, you can create a SNAT list and apply it to the VIP.

 

 

There is a general thought that using an active-active configuration is risky in that there is a tendency to load both BIG-IP's past 50% capacity. At that point, if one unit fails, then the remaining unit cannot handle the total load. Other people might have opinions, but we've never implemented active-active for any of our customers.
