The template I use on new installations
Tags: FreeBSD firewall pf
pf.conf
The open ports list is refined depending on the usage obviously… It is just a template:
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 egress from <jails> to <internet> -> (egress:0)
rdr-anchor "rdr/*"
set skip on lo
block return log
##### This firewall #####
block drop in on egress
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 egress proto tcp from <internet> to <myself> port { ssh, http, https, smtp, smtps, submission }
pass out from <myself> to any
##### VPNs #####
pass in on egress proto udp from <internet> to <myself> port 342
pass in on wg0 from <private> to <myself>
pass in on wg0 from <private> to <private>
pass out on wg0 from <private> to <private>
A pre-requisite of this sample is to have set an egress
group for your egress interface(s) like so in your /etc/rc.conf
:
ifconfig_vtnet0="DHCP group egress"
