Maximum sessions guidance?
-
I'm looking for what the max limit for sessions are on pfsense. I know it has a lot to do with Hardware specs and the type of traffic as well but in general is there some hard limit?
Can the firewall support 500,000 sessions or more?
Thanks, -
It's completely dependent on how much RAM you have. 1 state == 1k of RAM. You can adjust the size of the state table under System > Advanced.
To do 500,000 sessions, you'd just need ~512MB of RAM just for states, not counting other system processes, so to be safe you might say ~768MB-1GB+ for that level.
The rest is a factor of CPU and motherboard speed in terms of bandwidth/throughput and such. It's not as easy as saying "x sessions".

I knew the 1k=1 state baseline but Has anyone got pfsense running around 500,000 session in a production environment?

I've heard of people with 1M+ states. It's possible as long as you have the hardware to handle the load, and the bandwidth and number of users to make that many. :-)

Yes, many.
I've personally gotten a 2.0 amd64 install up to around 15-16 million states.
