Use OpnSense as Load Balancer

[nikkon]

Hi all,

Quick design question:
I have 2k+ websites/forums and I use Netscaler as load balancer in front for apache/Nginx/u name it

We reduce costs and we may thing to switch to pf sense/opnsense for this. My question is how many machines I can use (is there any limitation in this possible setup in terms of virtual servers definitions)
How many machines I can use in a CARP setup for this?


Thank you
M
