Hello.
I have an openwrt firmware installed in my router and I want to
configure a Home and a Guest interface.
So I have two internal interfaces(home,guest) and the external(eth1).
First I have to send all traffic from the two internal interfaces to
external(eth1) so that I can use one qdisc with classes which can
borrow rate from each other. Subsequently, I want to use the Tc-prio
tool to apply priority queuing and then I also want to limit the rate
of the external qdisc(eth1), so I use tbf scheduler ,as shown below.
It is very important for my project to define home and guest queues in
bytes and not in packets so I want to use BFIFO in my 3 prioritized
auto created classes and not pfifo_Fast and ifconfig method. So when I
add the 3 last lines of code the two internal interfaces do not have
network access, so I suppose that the iptables commands doesn't work
any more. Is it possible for you to point the problem here?
Thank you in advance,
