Hi Netfilter, Hope this is the correct list to email, else I’m eager to hear which route to take. Using netfilter-persistent package on ubuntu an iptables restart gives error when reloading iptables and a ipset already exists. Afaics -exist ought to work, but it still returns error code 1 and systemctl perceives this as an error. /usr/share/netfilter-persistent/plugins.d/10-ipset start Which runs: ipset restore -exist < /etc/iptables/ipset Still returns: ipset v7.15: Error in line 1: Set cannot be created: set with the same name already exists ipset restore -exist < /etc/iptables/ipsets ipset v7.15: Error in line 1: Set cannot be created: set with the same name already exists ipset create -exist vxs hash:ip family inet hashsize 1024 maxelem 65536 bucketsize 12 initval 0x9bb42fcc ipset v7.15: Set cannot be created: set with the same name already exists Also when directly using ipset create / restore I get an error where I expected it to be quiet because of the -exist. Looking forward to your reply, Respectfully Rob Bloemers
