[SOLVED]High CPU load - Pfsense 2.1+CP+multisubnet+ 300 plus MAC pasthrough
I would like to report something
I use pfsense 2.1 as intervlan routing to my campus
All LAN clients in VLANS are able to be pinged from WAN
Intervlan function seem to be working fine.
Then, I activated the captive portal to auth access to our hotspot VLANs ( we have 5 VLANs, one for each floor)
To provide ROAMING function , I use passthrough MAC function Auto entry, so when new user logged-in to one hotspot VLANs, his/her MAC are stored in passthrough MAC table, along with his/her username.
After users started to logged in, within minutes, lots of MACs are stored to the table
By this time, I started to see pattern of CPU spike every 60 minutes.
What do you guys think this is? Is this normal for Captive Portal with 300+ MACs in the passthrough table?
Thanks for all reply.
I think I found a solution from this thread
I did 2 changes:
1. Change WAN IPV6 Configuration, from DHCP to NONE
2. Advanced - Networking - IPV6, uncheck Allowed IPV6
Problem solved. I hope it will help other people.
