Where can i find net.link.ether.inet.allow_multicast
-
Hi
I have problems with Windows Network Load Balancing where multicast has been used.
In System General log I can see this "kernel arp: 03:bf:c0:a8:0b:e1 is multicast"
Where 03:bf:c0:a8:0b:e1 is the NLB mac address.But I can not ping from the virtual IP from the HA cluster setup and not from the local IP of the 2 firewalls in the HA cluster or the other way from the multicast IP.
And yes I use the newest version from today: 2.4RC built on Thu Aug 24 16:53:08 CDT 2017Thanks

Sounds like something that can be placed in System > Advanced, System Tunables
You can check the current value with:
sysctl net.link.ether.inet.allow_multicast
Either on the console/ssh or in Diagnostics > Command Prompt
The default looks to be 0.
You can manually set it with:
sysctl -w net.link.ether.inet.allow_multicast=1

Hi
That was the solution.But in 2.4RC this option is missing in System > Advanced, System Tunables
Also I could not login with SSH as I got an error that Putty could not understand the SSH key.
Thanks

So create it. You are not limited to what is listed there. You can do any sysctl that can be set after boot.
Those that must be present at boot time can be set in /boot/loader.conf.local

Hi
Thanks for letting me know about loader.conf.localBut it looks like there are a lots of features hidden. Where can I find a list over all the sysctl settings.
And thanks again

You probably want the FreeBSD docs for that.
