Inbound Load Balance Question

[rneily]

I've got inbound load balancing setup with 2 servers behind a pfsense box.  It's operating nicely, no problems with the machines going down and the pfsense load balancer removing the downed box form the active pool.

However, the one odd thing is that the number of incoming connections is not evenly distributed between the two servers in the pool.  Looking at the servers, I see up to 50 connections on one box, and only like 9 on the other.

Is there a reason for this?  It's not a big problem, since the load balancer is working, but I thought round robin would pretty evenly distribute the connections between servers in the pool…. Just curious as to why?

I does this roundrobin. Maybe some of the connections are staying longer open than others? Check the statetable by viewing pftop from the shell/SSH for these connections and how long they are established already or how new connections are balanced.

Anyone knows if features like "Weighted Round-Robin" "Least connections" or even "CPU Usage" for SLB will be implemented?

If/when PF supports them, maybe.

What would a suggested bounty for these features be?

first you have to talk to the develpers of pf ( pf is the firewall of freebsd that pfsense uses)
if they made that option in pf then the pfsense core team can make a option for pfsense to use it

so unless pf adds those options there is no reasen for a bounty
