OK, I'm trying to determine if the source address, using the FIB
(routing table), is a broadcast or multicast address. I'm making the
rash assumption that the daddr type is accessed by using the meta
pkttype in the output and forward chains:
> define wan0 = enp1s0
> iifname $wan protocol {tcp,udp} pkttype {broadcast, multicast} counter drop
Is there any way to do with for the source address using the FIB?
I need this to conform to BCP38 in my Linux router.
