Copy -in one of the init or init.d scripts, and make sure -it is set for auto-start for your OS. An actual reboot -is recommended. - -Once up and running, configure ip6tables to route -large packets destined to the desired IP to the netfilter queue. - -Example rule: - -``` -guest% sudo ip6tables-save | grep NFQ --A INPUT -d 2001:470:1f04:d63::2/128 -m length --length 1281:65535 -j -NFQUEUE --queue-num 1280 -``` - - -LICENSE -------- -GPLv2, due to the duplicated code from Hararld Welte's -libnetfilter_queue-1.0.2/utils/nfqnl_test.c (included). - - |
