There's another TCP/IP protocol-related limitation that you should consider if you explicitly translate client source IP addresses (Source NAT), before the requests are routed to BigIP.
The TCP/IP protocol has a limitation of 64k unique sessions
from a single IP client (i.e. 1.1.1.1), to the same Server IP/Port listener (i.e 2.2.2.2:443)
. There's a dedicated 64k-unit-size range for TCP source ports that can be used by the client.
