Fedora 31. nftables-0.9.1-3.fc31.x86_64
The same ingress rule works on the ethernet port, but not on wireless.
This works:
cat ipv4-netdev-asterisk
# /opt/nftables/ipv4-filter-asterisk
include "/opt/nftables/whitelist1"
include "/opt/nftables/ip.blacklist1"
table netdev netdev1 {
set whitelist {
type ipv4_addr
flags interval
auto-merge
elements = $whitelist_ips
}
set blacklist {
type ipv4_addr
flags interval
auto-merge
elements = $blacklist_ips
}
chain ingress1 {
type filter hook ingress device enp5s0 priority 0; policy accept;
udp dport { 6000-31000 } accept comment rtp_ports
#accept whitelist
ip saddr @whitelist accept
tcp dport { 3478, 5349, 554, 5222, 5269, 19294 }
counter accept comment "stun stun-tls rtsp and gv"
udp dport { 3478, 4893, 19295, 19302 } counter accept
comment "stun and gv"
#drop blacklist
ip saddr @blacklist counter drop
}
}
But if I change the device in the ingress1 chain to wlp4s0, which exists:
ifconfig | grep -A 1 wlp4s0
wlp4s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 10.0.0.61 netmask 255.255.255.0 broadcast 10.0.0.255
it fails.

Just to repeat: the only change is the device. The other files are all
the same.
