Still having this issue on a machine updated from 2.1.5 to 2.2.
Prior to upgrading, the setup did work, although the reported values were higher than the real usage (https://redmine.pfsense.org/issues/1974#change-16421).

Information about my setup:
2.2-RELEASE (amd64)
This is a VM running on a Xenserver. /etc/fstab was converted to UFS labels. Interfaces were reassigned during first boot after upgrade.
Using MAC authentication with the "RADIUS MAC authentication" option enabled in CP.

Using 2.2-RELEASE (amd64) and this bug still exists, its not counting.

This is still a problem in 2.2.2. Byte counts are all still zero!

I'm about to start digging through the code now, and will submit a pull request if I find anything.

I put some debug code into /etc/inc/captiveportal.inc and got this result:

Unfortunately I'm not a C programmer so I can't look into what the problem with pfSense_ipfw_getTablestats is.

Can you run the same request but from CLI with ipsec -x 2 table 1 entrystats 10.10.8.139?

Tell me what do you see?

I think your problem is on the mac address format it should be specified by : rather than -

Thanks, confirmed that is the issue.

)

We use the dropdown in captive portal settings to select IETF style MAC addresses, because that is what our RADIUS server expects. The C code should be separator agnostic, or the PHP code should sanitize it beforehand.

It should fix the issue though you would have to clean up all your existing entries from CP and have them authenticate again.

UPDATE: With proper patch.
UPDATE2: Which fixes the root cause.
