RRD Graph issue showing Opt traffic in WAN RRD Graph

FJSchrankJr

I've been noticing very interesting trends in traffic between 2 WAN interfaces. WAN and OPT1 (WAN2). The outbound traffic in RRD shows similar trending between the 2, and today when OPT1 went down, the drop in traffic is also visible on the WAN graph.

So, because this firewall is setup as NAT is it possible that WAN traffic graphs are including WAN traffic + OPT1 traffic? It was a very strange issue and has had me confused. I was looking towards a routing issue but came up with nothing. Something else thats very interesting is the traffic in Traffic Graph is not consistant with the traffic in RRD unless you add both interface traffic together, then RRD appears to be accurate.

This is on a pfSense 2.0-RC1 built on Wed Jun 15 19:13:09 EDT 2011. Thank you for your help guys!

confirmed, everytime WAN2 (OPT1) has a traffic burst, the RRD for WAN shows the burst too but the traffic for WAN and WAN2 are different, WAN appears to be WAN traffic plus WAN2 traffic added together.

I should note I am using virtual IPs on both interfaces setup through CARP.

This only applies to outbound traffic, inbound traffic in the WAN and WAN2 rrd is accurate. For some reason it looks like WAN RRD is inaccurate only for outbound traffic. If I were to disconnect WAN2 and drop all WAN2 traffic, WAN RRD shows only WAN traffic but it does show the big drop now that WAN2 is down and all traffic from WAN2 gets subtracted.

Somehow, the data is conflicting but the routing is fine and everything else works as it's supposed to. I found a few bug reports in bugtracker about RRD graphs with outbound traffic and I am wondering if it's the same deal here.
maybe it was fixed in a newer build? thanks all

another pfsense firewall we run with public IPs in a transparent bridge is showing WAN in traffic on the out traffic.

I am also having the same problem, 2 WAN facing interfaces (WAN and OPT1), rrd traffic graph for WAN shows WAN+OPT1 upload data.

Is there a fix for this?

Interesting that the dynamic traffic graph does not have a problem, only the rrd graphs.

It's listed in the bug tracker and it might have been resolved in 2.0.1, traffic is not affected though and it only appears to happen in a multi-wan setup. I will check the bug tracker and let you know.

I checked the bug tracker but didn't see that it was resolved. I will take a look within the next few days and try to locate/fix the problem.

It only happens on a multi-wan setup and the wan graphs also include traffic from the other wan interfaces. Is this what others are seeing? The more info you can provide the better. Thank you guys.
