## 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
```
