I Setup vnstat on my second Router (Both Router using LEDE 17.01.0 Stable) on the same Router-Hardware like my first router.
The First router is connected to the WAN directly (using pppoe-wan Interface). The second one is connected on the first LEDE-Router using DHCP-Client (eth0).
Problem: On the first Router vnstat monitors its traffic just fine without any trouble: loading 20gigs and vnstat shows 20 gigs rx.
But on the second LEDE-Router which using dhcp-client and NOT pppoe, vnstat has missing traffic (same vnstat config as on first router).
On second router: If I am download 10 gigs file, vnstat shows only 200MB on rx.
I changed and tested everything in vnstat.conf (UpdateInterval, PollingRate etc) but nothing helped.
But can It be thats not vnstat mistake ? Today I tested the following on the second Router:
Restarted the router (to be sure traffic data is flushed in luci -> network -> interfaces).
Downloaded again 10 gig file, but now not only vnstat shows the wrong traffic (again 200 MB rx).
If I take a look on luci webinterface (under network interfaces), the LAN interface bridge shows it wrong also (200 MB too)...
So the mistake is not from vnstat ?
Any workaround to fix this ?
Hardware: Both TP-Link Archer C7 v2
EDIT: has it to do with wrong VLAN setup maybe too ? on LEDE factory settings all ports are on VLAN ID 1 - untagged except WAN port and CPU (are the same on Archer c7): these two are on VLAN ID 2 untagged
now I have all ports and CPU / WAN, all on the same VLAN: VLAN ID 1 untagged
