First question is about the non-routable / reserved address spaces.
Are _ALL_ of them needed or just the four mentioned in the pf manual?
# Block all inbound traffic from non-routable or reserved address spaces
# RFC 1918 private IP
block in quick on rl0 from 192.168.0.0/16 to any
block in quick on rl0 from 172.16.0.0/12 to any
block in quick on rl0 from 10.0.0.0/8 to any
# loopback
block in quick on rl0 from 127.0.0.0/8 to any
block in quick on rl0 from 0.0.0.0/8 to any
# DHCP auto-config
block in quick on rl0 from 169.254.0.0/16 to any
# reserved for docs
block in quick on rl0 from 192.0.2.0/24 to any
# SUN cluster interconnect
block in quick on rl0 from 204.152.64.0/23 to any
# Class D & E multicast
block in quick on rl0 from 224.0.0.0/3 to any
The manual of pf only writes about:
priv_nets = "{ 127.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12, 10.0.0.0/8 }"
It's my guess I can leave them out _OR_ I include them in $priv_nets.
If I do that the rule becomes very large.
Second question: can I rewrite the pf.conf rule (with a "\") like this:
priv_nets = "{ 127.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12, 10.0.0.0/8 \
0.0.0.0/8, 169.254.0.0/16, 102.0.2.0/24, 204.152.64.0/23,
224.0.0.0/3 }"
