Hello, I am trying to change the OS fingerprint with iptables. Here are two rule set which I have constructed to do the same ```````` iptables -t mangle -A PREROUTING - -j PERS --tweak dst --local --conf example/win9x.conf iptables -t mangle -A OUTPUT -j PERS --tweak src --local --conf example/win9x.conf ```````````` But it throws an error like `````````` iptables v1.4.2-rc1: Unknown arg `--tweak' Try `iptables -h' or 'iptables --help' for more information. ``````````````` What might be the problem here ?
