Max Connections?



  • Hi,

    I would like to know What is the max number of connections/state/flows that can be support by pfsense?  Thanks.

    The only limit is your RAM - the number of active connections is governed by the state table size, and 1 state = 1Kb of RAM.

    You can increase the limit under System > Advanced (On the Firewall/NAT tab on 2.0), and you can raise it up higher, just don't set it larger than the amount of RAM you have.

    Thanks.  I am always wondering, Can I use the amd iso to run in X64 intel CPU?

    Yes, amd64 is just the generic term for FreeBSD's 64-bit architecture. It works on AMD and Intel 64-bit CPUs.



  • Is there a limit to the amount of RAM that pfSense can address?

    Thx.



  • The limit is set by 32 or 64 bits architecture, not by pfsense.

    32 bits will be 3.5 gb
    64 bits will be 120gb (Google told me that ;))
