Hey guys,
I know that this is a question that will need to be directed to the
PFSense router team but I was hoping I could get some information on the
issue from you guys first to help narrow down the cause. So here goes.
I have a basic LVS-DR balancing ports 80 and 443 between two real
servers using weighted round robin with persistence engaged. In the
event of a real server crash ipvsadm shows that the failed server's
weight is now 0 and if I hit the the VIP from my LAN my request is
routed to the remaining server without issue.
The problem arises when I perform a failover test using the WAN IP that
I have routing to the VIP using NAT. In this case, the request is still
trying to be routed to the crashed server. I came across this patch that
addressed the issue in LVS itself.

What I am wondering is if you can give me some idea for how that patch
fixed the issue so I can convey the information to PFSense and see if
they have a mechanism I can trigger manually to achieve the same effect?
Thanks for any info you can provide,
