ask for information on pf.conf

Hello

I did add ipv6 and I wonder if my pf.conf filter ipv6 traffic.

And I add the line in FAQ for ftp but it does not work maybe because of 
the trunked interface but I don't know what to do to correct that.

Here the pf.conf:#       $OpenBSD: pf.conf,v 1.55 2017/12/03 20:40:04 
sthen Exp $
#
# See pf.conf(5) and /etc/examples/pf.conf

set skip on lo
anchor "ftp-proxy/*"

block return    # block stateless traffic
#pass           # establish keep-state

# By default, do not permit remote connections to X11
block return in on ! lo0 proto tcp to port 6000:6010

# For fragmented packet and antispoof
match in all scrub (no-df)
antispoof for { axen0 }

# For ICMP
pass inet proto icmp all

# Personal rules - traditional block all + whitelisting used
tcp_admin = "ssh ntp auth domain"
tcp_files = "www https 70 1965"
tcp_mail = "imap imaps smtp smtps submission"
tcp_services = "{" $tcp_admin $tcp_files $tcp_mail "}"
udp_services = "{ submission domain ntp }"

pass out proto tcp to port $tcp_services
pass in proto tcp to port domain
pass proto udp to port $udp_services

#ftp
pass in quick on {trunk0 axen0 qwx0} inet proto tcp to port 21 divert-to 
127.0.0.1 port 8021

# For avahi
pass in proto udp from any to 224.0.0.251 port 5353 allow-opts

It can have more problems, please comment.

Bye
