Data still being used on WAN set to 0%

[ceromus]

I have a 4g modem connected and in wan balance its set to 0%, i have 2 other isps so its configured like this:
wan1 is 70%
wan2 30%
4g is 0%

The 4g is still using data, approximately 7GB a day but once data usage causes throttling its about 3GB per day. I can see it in reports Network > Data usage per day (by interface). I have no route rules set to use the 4g connection and i do not have daily drops of WAN1 and WAN2 service.

What could be causing this kind of data usage?

Bypassed traffic does not follow WAN balance rules.

Just look at the network report to see what traffic is using the cell connection.

network report as in sessions? im trying but I cant find anything using that server interface, i see a lot of None [0] though but nothing using the 4g interface.

Oh I think I found out what it was, I had an http test setup and each test was pulling like 255KB every 3 seconds.
