Does nobody have an idea why the vnstat values are quite far off the actual traffic passing through the system?

I don't know if this would work but I can say it is ill advised from a security standpoint..
You don't want your internet facing firewall to do anything but routing and network tasks.
iSCSI file serving is something you want to do behind pfSense not on top of it.

What should I be looking for?

In Germany it is common that many of the ISPs are cutting the Internet connection once a day, could this be the
point you should also looking for?

If there is a double NAT situation you could try out to set at the pfSense WAN settings a satic IP address from the
network of the router in front of that pfSense box. Because the DHCP lease will be out after xyz minutes/days/weeks
or so on.

Internal:

The ARP table as named above Squid & SARG perhaps

External:

CentOS and NAGIOS2 TclMon on an APU, NUC or other small device On a small external device such the RaspBerry PI or the netgate MinnowBoard Turbot series and a Linux or FreeBSD
OS on it with CACTI and MRTG.

I learn that release 2.4 will have no nanobsd image.

32Bit and NANO BSD are gone, but there fore we got ARM support and some other nice things, so it was nothing
less but more changed against other things that are available now.

If I install pfsense to a compact flash drive, how can I reduce writing to CF?

Alternately you may go with a 4 GB or 8 GB IDE flash module or with a IDE SSD that might be the best option in my eyes.

Currently, I have a old PC with a 2G CF card with nanobsd image installed on a IDE slot, it works great for more than 5 years.

32Bit hardware? This might be also running out too! So newer hardware will be not so really high in price,
the APU2C4 or the SG series might be holding for Internet account with lower speeds.

Is it possible to have a similar installation like this after 2.4 released, I mean with minial CF wear out problem?

As stated above you should try out a small IDE SSD.

Thanks for you reply. I will only need snort package. Is snort only write to /tmp or /var?

What is your Internet connection speed?

BTW: How much disk space is required for a full pfsense install, I cannot find it documented
anywhere

pfSense and snort is able to install on a small 16 GB mSATA storage. The APU2C4 is able to get around
for ~199 € and the SG-2220 is able to get for $299.

Wonderful. Thank you again for sticking by a novice like me.

I'm not aware of anything other than dpinger, but you can specify the IP that it pings to check connectivity.  While generally pinging the gateway makes the most sense, if it's not reliable you can use something else.  For example, you could ping one of Google's DNS servers live 8.8.8.8.

yeah, that is the process i was trying to automate on my switch.

Apparently some have had success with simply setting pfSense WAN to DHCP and then you don't have to run through the process every 14 days.

Honestly though, I agree. All of the options sound really hacky and reliable.

Everything goes out the window if the connection resets for any reason and I'm not home to fix it.

If I don't hear of something more reliable I'll probably just run the gateway in their crappy pseudo-bridge mode.

0/ You don't need sshd enabled to copy files via SCP/SFTP.
1/ Windows does not support the above natively.

There you go…  :)

I suspect it's something to do with the ip profile in the DSLAM that get's updated when the session is re-started.

Nothing fancy… it's 2.4.0RC as shipped.

The firewall has now reset itself and is back online. There's nothing useful in dmesg or system.log.

Only package installed is AutoConfigBackup.

I'll try digging more with ps next time it happens. I might try rigging up monit to do it for me.

I was hoping there would at least be some pfsense-related reason for dc having been called… now I'm somewhat unsettled.

Thanks, everyone…

Thanks, Jim.

My install has been upgraded many times since 2.1.x, and I've got a tunnel defined but disabled.  We don't use IPSec at all and never have.  I thought it was there by default, but most likely I created it while playing years ago and forgot about it.  Why I would disable it instead of deleting it is a mystery.

So I will agree that its clunky.. The only thing it has going for it is cheap, and it can handle my new 500/50 at speed.

I am running the latest 4.4.8 code.. But I have left my pfsense vm running to handle dhcp and resolver - those features in the usg are pretty bare.. And no resolver at all.  Just forwarder mode. So good luck running your own dns on it, etc.

And your correct anything like openvpn or HE tunnel has to be done at the cli - which wouldn't be the end of the world.  But if controller does a re provision seems that all gets wiped.. If your a simple home user with 1 network and no need for vpn or tunnel (it doesn't seem to do any ipv6 on its own) might be a good thing.  But from the day I have had to play with it seems more a toy than the mature very feature rich easy to use pfsense.. The dpi stuff looks interesting, but that seems to be the only thing its got going for it.  And with pfsense you could just install ntopng and get all that kind of info as well, etc.

But again thanks for your thoughts and appreciated your willingness to test its top limit, etc.  Prob going to have to live with it till nov when I can replace it real pfsense hardware ;)  But after that it will be either on my self collecting dust - or looks like I might have some buyers for it ;)

Try doing static port?

I'm seeing the same thing - 502 errors. I'm running three sites all of them worked perfect until 2.4.0-RC changed from bsd 11.0 to bsd 11.1 (a few days ago)
Strange thing is that it's only one site that have the problem. The problem site is the site with most users.

Hi,

I am also interested in what Domotz can do, but like AR15USR I am concerned about the security issues associated. Since Johnpoz mentioned there is a local server, I was wondering if it makes sense to block all outbound communication of the Domotz server and use VPN. Does anyone think this will work?

You would probably want to examine the firewall logs for the time it is not reconnecting and see if anything is blocked.

You might also want to look at the state table and see what states are established on behalf of the PBX and see if that gives you any indication why it isn't working.
