#11272 closed enhancement (invalid)

integrate "rpfilter" module of iptables 1.4.13

Reported by: lsching17@… Owned by: developers
Priority: normal Milestone: Barrier Breaker 14.07
Component: base system Version: Trunk
Keywords: iptables rpfilter Cc:


in ipv4 world, there are sysctl variables net.ipv4.conf.*.rp_filter which perform reverse path filtering to detect invalid source address.

However, this is not available to ipv6.

A "rpfilter" module is available since Linux 3.3 and iptables 1.4.13 which allow user to perform reverse path filtering in ipv4 and ipv6.


iptables -A PREROUTING -t raw -m rpfilter --invert -j DROP
ip6tables -A PREROUTING -t raw -m rpfilter --invert -j DROP

Please provide it in package "iptables-mod-extra" or somewhere else.

+1 - please update openwrt to include iptables 1.4.13, it's a core package for a router and should be up to date with the kernel!
