Hi, As I wrote before I'm testing with 'iptables 1.6.0'. While looking which files I would need to backup so I could run some tests on my production machine I found that 'iptables 1.6.0' and current 'ebtables 2.0.10-4' are building duplicate files. 'ebtables' puts them in '/usr/lib', 'iptables 1.6.0' in '/lib/xtables': libebt_802_3.so libebt_ip.so libebt_log.so libebt_mark_m.so What would be the best way to handle this? Comment in (which?) rootfile? As an info: 'iptables 1.6.0' was build with the new option '--disable-nftables', otherwise build failed: "fatal error: libnftnl/rule.h: No such file or directory". Best, Matthias
