Hi All,

I'm trying to find out max number of secure associations (SA) one VPN gateway is able to handle.
I've built strongswan with the load-tester plugin and can't get more then 4500 SAs:

ipsec status | head -1
Security Associations (4595 up, 587 connecting)

Is there a way to get more? What's the main blocker?
I have already set block_threshold = 0 on the server.
Also tried multiple clients.

Thanks for any help,
