Add support for network exclusion parameter
dastergon opened this issue · comments
Hi,
It would be great to see an exclusion parameter in comcast
which will exclude the rules to a specific network.
e.g., Apply the delay to everyone but 192.16.0.10:
comcast --device=eth0 --latency=250 --target-bw=1000 --packet-loss=10% -exclude-network 192.168.0.10
or to a specific CIDR:
comcast --device=eth0 --latency=250 --target-bw=1000 --packet-loss=10% -exclude-network 192.168.0.10/24
Example of tc command for network exclusion of packets of 192.168.1.15 with destination port 9001:
tc filter add dev eth0 protocol ip parent 1:0 prio 3 u32 match ip src 0/0 flowid 1:3
tc filter add dev eth0 protocol ipv6 parent 1:0 prio 4 u32 match ip6 src ::/0 flowid 1:3
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip dport 22 0xffff flowid 1:2
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip sport 22 0xffff flowid 1:2
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip src 192.168.1.15 match ip dport 9001 0xffff flowid 1:2
tc filter add dev eth0 protocol ipv6 parent 1:0 prio 2 u32 match ip6 dport 22 0xffff flowid 1:2
tc filter add dev eth0 protocol ipv6 parent 1:0 prio 2 u32 match ip6 sport 22 0xffff flowid 1:2
tc filter add dev eth0 protocol ipv6 parent 1:0 prio 2 u32 match ip6 dport 9001 0xffff flowid 1:2
Thanks,
