I'm switching from iptables+ipset to nftables, and as part of it, I need to import a set containing ~2400 IPv6 networks. The file looks like this: define elems = { 2001:123::/31, ... } table ip6 mytable { set myset { type ipv6_addr flags dynamic,interval elements = $elems } chain output { type route hook output priority -150; ... ip6 daddr @myset reject } } And then "nft -f myfile.nft" fails with netlink: Error: Could not process rule: No buffer space available -- Best regards, lilydjwg
