## pf.conf
The open ports list is refined depending on the usage obviously... It is just a template :
```conf
ext_if=vtnet0
scrub in all
table <jails> persist
table <myself> const { self }
table <private> const { 10/8, 172.16/12, 192.168/16, fd00::/8 fe80::/10 }
table <internet> const { 0.0.0.0/0, !10/8, !172.16/12, !192.168/16, ::/0, fe80::/10, !fd00::/8 }
##### Basic rules #####
nat pass on $ext_if from <jails> to <internet> -> ($ext_if:0)
rdr-anchor "rdr/*"
set skip on lo
block return log
##### This firewall #####
block drop in on $ext_if
pass inet proto icmp all icmp-type unreach code needfrag # MTU path discovery
pass inet proto icmp all icmp-type { echoreq, unreach } # echo reply
pass inet6 proto icmp6 all
pass in on $ext_if proto tcp from <internet> to <myself> port { ssh, http, https, smtp, smtps, submission }
pass out from <myself> to any
```
