Hi,

I have a "problem" with my pfsense when i'm using CARP.

Let me summon it up:

physical server dell r610 running vmware esxi 5.0, with a vmware pfsense on top.

My setup:
PfSense
OPT1: 192.168.1.1
OPT2: 192.168.2.1

Servers:
Server A: 192.168.1.10, gateway 192.168.1.1
Server B: 192.168.2.20, gateway 192.168.2.1

when i transfer a file from server A to server B i get full usage of my 1gbit link in my HP switch.

When i enable carp on OPT1 so the conf looks like this:
OPT1: 192.168.1.254 // VIP 192.168.1.1
OPT2: 192.168.2.1

Then i only get half the performance (470mbit). Is this expected behaviour? If i change the gateway on the server A to 192.168.1.254 the transfer rate increases to 1gbit...

I've just attached a screenshot of the interface graph in the switch...

I've just noticed that if i change the VIP in PfSense from CARP to IP Alias, then the problem disappears.

Any thoughts?
