yes, I know the history of openwrt and freewrt and I like freewrt better, because 'nvram ...' and other things of openwrt are not really unixlike. So I have a wish for the future. If it's possible (and stable), please integrate libipt_physdev.so, ebtables.ko and physdev.ko. Newly ebtabes.so include the patch bridge-nf, which enables to use iptables between bridged devices. dmesg should print: --- Bridge firewalling registered Ebtables v2.0 registered --- regards, Sebastian _______________________________________________ freewrt-users mailing list freewrt-users@freewrt.org https://www.freewrt.org/lists/listinfo/freewrt-users
