What happens if you run /usr/local/bin/vnstat from the cli and have you got Status_Traffic_Totals installed ?

The traffic isn't right for my LAN interface as I think it puts the parent interface into promiscuous mode, my LAN interface is just used for switch & Wi-Fi management no way the total is 56.80 GiB.

Access Point What's the point of doing it?

Ok. Thanks for the response. I will try it.

@SammyWoo:

@H20FRKS:

SammyWoo, are you saying building a pfSense server with better hardware will not resolve the through put issue I have?

Just the opposite.

Great thanks! I will continue my efforts to understand pfSense better and work on building a server.

Hi Steve,

I fully support your statement. Do not upload files to your firewalls from an unknown sources.

The driver was compiled on freeBSD 11.1 amd64 release.

Kind Regards,
Nick

I was able to get back into the router after setting my static IP address (and then unsetting it afterwards).  I was able to restore my router using a backup to the point BEFORE I tried to implement OpneVPN.

This issue is resolved.  Thank you all for your help.

Reflashed the BIOS to 4.0.12.

Ran a memtest for a week, 0 errors.

Stopped the memtest this morning. Let PFSENSE boot, withing 5 minutes it crashed. Below is the log in the pastebin link.

If you have Gold membershiop or Book access then:

Otherwise there's troubleshooting tips here: https://doc.pfsense.org/index.php/LDAP_Troubleshooting

Yes i Have , i found it

Many Thanks Steve

USB Ethernet is notoriously variable. Usually not too much we can do about that other than swap it out.

Try increasing the number of available php processes. In System > Advanced > Admin Access set 'Max Processes' to 4.

That may resolve it if it's something temporarily using resources or it may just increase the time between issues.

Hi,

the modem isn't the source of the problem. Since it doesn't handle the pppoe session the settings for MTU are greyed out.

Here's a snippet of my pfsense config file:

        <ppps><ppp><ptpid>0</ptpid>                         <type>pppoe</type>                         <if>pppoe0</if>                         <username>myusername@netaachen.de</username>                         <password>youwontbelieveit</password>                         <provider>netaachen</provider>                         <idletimeout>0</idletimeout></ppp>                 <ppp><ptpid>1</ptpid>                         <type>pppoe</type>                         <if>pppoe1</if>                         <ports>vtnet0</ports>                         <username>myusername@netaachen.de</username>                         <password>youwontbelieveit</password>                         <provider>netac</provider></ppp></ppps>         <interfaces><wan><enable></enable>                         <if>pppoe1</if>                         <spoofmac></spoofmac>                         <ipaddr>pppoe</ipaddr>                         <ipaddrv6>dhcp6</ipaddrv6>                         <dhcp6-ia-pd-len>16</dhcp6-ia-pd-len>                         <dhcp6usev4iface></dhcp6usev4iface>                         <mtu>1492</mtu></wan> [...]</interfaces>

What's REALLY weird is that the password I find in the config is different to the one I find in my tcpdump/wireshark recordings. WTF? How can that be?
Session is coming up fine though.
What I haven't found is some RFC explanation about how MTU is being negotiated.

This is what my interface is saying btw:

pppoe1: flags=88d1 <up,pointopoint,running,noarp,simplex,multicast>metric 0 mtu 1442</up,pointopoint,running,noarp,simplex,multicast>

Ping6 seems to verify that, since 1442 - 40 (IPv6) - 8 (ICMP6) are actually 1394 which is the maximum packet size I can ping6.
Confusion starts to grow. :-\

Edit:
I took a closer look at the tcpdump and what I found is that the Router Advertisement is saying 1442. Why would the provider want to do this? It looks like a faulty setup Router Advertiser to me.

I asked about this just recently..  https://forum.pfsense.org/index.php?topic=145261.0

and using openvpn seems like something people would expect you to use from home-to-work. (but that is already setup by our sysadmin)

So I'm guessing your asking how to setup this - because you do not have this feature today.

Check out this: https://www.ceos3c.com/2017/04/10/configure-openvpn-for-pfsense-2-3-step-by-step/

Well, you have no choice but to VLAN from something to get the Wireless AP behavior you desire. But that does not have to be done on pfSense. A switch could do it. pfSense would have two physical interfaces to two untagged ports on the different VLANs in that case. But why not just VLAN it?

If you don't want to mix tagged and untagged traffic on a physical interface, don't. Just leave the untagged interface unassigned.

Thank you for your response. I will try and keep notes on when it occurs throughout the day tomorrow and see if anything odd is in the system logs.

@viragomann:

ping and traceroute maybe do well. ICMP is a stateless protocol. The problems with that come if you establish a stateful connection.

So I'd try one of the suggestions.

OK, thanks for bearing with me! That one got through, I can just about picture how that makes a difference with how things are flying around.
