on QoS.asp there is Services Priority section. Use ip_icmp (ndpi l7) filter and give it exempt or maximum.
Or, you can do it from console, something like this:



Code:
iptables -t mangle -I FILTER_OUT -p icmp -m length --length 64:76 -m limit --limit 2/s --limit-burst 5 -j CLASSIFY --set-class 1:100
