A little problem i have with CIS in general are not if are firewall related.
VPNs in general installs virtual lan adapters to work, cis don’t detect it properly and register traffic outgoing from Openvpn and normal lan adapter (real) as one. So CIS bandwidth meter duplicate the traffic (visually).
I have test software like cfosspeed and glasswire perfectly registering traffic out from the virtual adapter, and not double times.
Anyone got similar issues ?
