Hi, Last weekend, I replaced my router in my home as the old one showed hard disk health warnings.
In short, by using /etc/nftables.conf, RPi4B seems able to filter packets at 600 Mbits/sec, where %irq of "atop" reaches 90% and M=1,000,000. Packet processing capability depends on the complexity of tasks. The router tunnels IPv4 packets over IPv6 by MAP-E (*). MAP-E consists of two steps: (1) IPv4 NAPT (Network Address and Port Translation) (2) Tunneling (e.g. by ip -6 tunnel add $TUNDEV mode ip4ip6 remote $BR local $CE dev $WANDEV encaplimit none) As the sets of usable ports by NAPT are discontinuous in MAP-E, the filtering rule is very complex (attached at the bottom), nonetheless, RPi4B is able to handle packets at a satisfactory speed, which is a surprise. (*) Explanations of MAP-E: https://en.wikipedia.org/wiki/Mapping_of_Address_and_Port or https://www.slideshare.net/akiranakagawa3/20150304-apricot2015apnicfukuoka Best regards, Ryutaroh Matsumoto /etc/nftables.conf: #!/usr/sbin/nft -f flush ruleset table ip my_notrack { chain PREROUTING { type filter hook prerouting priority raw; ip saddr 192.168.1.0/24 ip daddr 192.168.1.2 notrack ip saddr 192.168.1.2 ip daddr 192.168.1.0/24 notrack } } table inet map_e_filter { chain PREROUTING { type filter hook prerouting priority filter; iifname ip6tnl1 meta nfproto ipv6 log prefix "Error: ipv6 in tunnel!
