Trouble increasing kern.ipc.somaxconn

[stvboyle]

With the default install of pfSense kern.ipc.somaxconn=128.

This is shown by sysctl -a | grep kern.ipc.somaxconn :
kern.ipc.somaxconn: 128

One can increase this value from the command line by sysctl -w kern.ipc.somaxconn="4096" :
kern.ipc.somaxconn: 128 -> 4096

I should be able to add kern.ipc.somaxconn="4096" or kern.ipc.somaxconn=4096 to /boot/loader.conf or to /boot/loader.conf.local or to /etc/sysctl.conf.  Unfortunately, when I make those changes and reboot, I still see kern.ipc.somaxconn: 128.  The boot time changes do not seem to be taking effect.  How can I change somaxconn at boot time or why are the settings not taking effect?

Thanks!!

Your change needs to go into sysctl.conf. On pfSense 2.0 snapshot builds sysctl setting can be changed through web GUI: System -> Advanced, click on  System Tunables tab.

I suspect sysctl.conf gets overwritten on reboot.

Using System Tunables made all the difference.  Thank you.
