firewall: T970: Add firewall group domain-group
Domain group allows to filter addresses by domain main
Resolved addresses as elements are stored to named "nft set"
that used in the nftables rules
Also added a dynamic "resolver" systemd daemon
vyos-domain-group-resolve.service which starts python script
for the domain-group addresses resolving by timeout 300 sec
set firewall group domain-group DOMAINS address 'example.com'
set firewall group domain-group DOMAINS address 'example.org'
set firewall name FOO rule 10 action 'drop'
set firewall name FOO rule 10 source group domain-group 'DOMAINS'
set interfaces ethernet eth0 firewall local name 'FOO'
nft list table ip filter
table ip filter {
set DOMAINS {
type ipv4_addr
flags interval
elements = { 192.0.2.1, 192.0.2.85,
203.0.113.55, 203.0.113.58 }
}
chain NAME_FOO {
ip saddr @DOMAINS counter packets 0 bytes 0 drop comment "FOO-10"
counter packets 0 bytes 0 return comment "FOO default-action accept"
}
}
