--- Comment #1 from Phil Sutter <phil at nwl.cc> ---
As per the one reply on stackexchange, raw sockets will bypass iptables.

Using nftables with its egress hook solves the problem, though:

table netdev t {
    chain c {
        type filter hook egress device "eth0" priority filter;
        udp dport 53 counter drop
    }
}

This snippet works in dropping any UDP packets sent via eth0 with destination
port 53, even with using a raw socket.
