We had a similar challenge. My advice would be to leave all the filesystems as
is - and add the 'sync' flag.
It slows down disk access - but makes the filesystem resilient to power
outages. See sync option - https://man.openbsd.org/mount

pass *in* proto tcp from any to mail.example.com \
port { 25 80 110 143 443 587 993 } synproxy state
How hard can that be?
A message saying synproxy is applied inbound and not outbound is necessary for
those which might assume that synproxy is being applied eitherbound.

Hi Tom,
I would recommend debugging using "unbound-control stats_noreset" and
referencing the unbound configuration documentation at
https://www.nlnetlabs.nl/documentation/unbound/unbound.conf/

Hi Cameron,
As a first guess, I would consider changing / implementing "set optimization".
This made massive difference on our customers satellite internet connection.
man pf.conf

Hi Kenneth,
It was staring me in the face and I did not see it. I shot myself in the foot
and didn’t realize it.
Thanks heaps for your support.

Hi All,
I am hoping to create a pf.conf configuration that has VLAN’s and NAT via the
same (physical) interface. The hardware is only capable of having a single
Ethernet interface.
vlan100 is an isolated network to setup servers and is connected to a switch
that is setup for vlan100 and vlan
It maybe possible that disk IO is saturated. (i.e. more writes than the
physical disk could handle).

I guess it boils down to a matter of preference and business requirements.
"slow writes" vs "no writes".

I have been in a similar situation of power being unreliable and no UPS, so I
sympathize.
This is how I have achieved RO filesystem (default partitions)
1. Add to /etc/fstab
swap /dev mfs rw,-P=/dev,-s=32m 0 0
2. Create RO Script
#!/bin/sh
UP=$(( $(date +%s) - $(sysctl
FWIW: We experienced "sendto failed: No buffer space available" as well. QOS is
not configured, but the firewall is connected to a satellite link that drops
between 5-10% packets average. The explanation fits in with our situation.

Sometimes I have made the mistake of dd if=/dev/zero of=/dev/sd2c - instead of
dd if=/dev/zero of=/dev/rsd2c - or worse dd if=/dev/zero of=/dev/sdc. These
kind of errors have filled /dev (or ultimately /)
Play over from my Linux days.

Hi All,
Without *block return label "block stateless traffic"* and *pass # establish
keep-state*, my NAT / redirect rules from external into LAN do not work.
Neither do rules that permit RDP to Windows Workstations on Tun0 interface.
FWIW: Wireguard uses this tun0 interface.
