PfSense on esxi 6.7, can get it to work propperly.

three

This is a specific of ESXI. If empty, VLAN are NOT supported. 4095 allows ALL VLAN numbers from the VM. I still get confused about VLAN, tagged, untagged, etc. But this should work,

kiokoman

indeed 4095 means that you set your vswitch as a trunk port letting any vlan pass through

marcel1988

Yes, this did the trick :)

marcel1988

so after a few day's working perfectly.
it now randomly stops working.

In the PfSense VM i see this:

When i reboot the VM everything works again.
What can this be?

kiokoman

try to reinstall open-vm-tools
maybe do a fsck also

marcel1988

@kiokoman

i have reinstalled the open-vm-tools and nothing changed
what you mean by fsck?

And what about the new update?
i'm now on:

2.4.4-RELEASE-p3 (amd64)
built on Wed May 15 18:53:44 EDT 2019
FreeBSD 11.2-RELEASE-p10

kiokoman

fsck: from console is option 5 and F key ( F: Reboot and run a filesystem check )
and yes, upgrade to 2.4.5

marcel1988

ok now i understand what you mean. i just did that a couple of hours ago and it seems to work again.
What about the update?

after the update i need to reinstall vm-tools again? and another fsck?

kiokoman

nope, no need, make a backup of your config just in case and do the upgrade

marcel1988

Still this is not working fine. My internet disconnects every 4-5 hour.
So can you please check my settings and tell me if the are right:

First off all, the network settings:

ESXI WAN settings: + VLAN ID 4095
ESXI LAN settings:
PfSense settings:

Cable managment:

WAN T-mobile > WAN Port intel NIC ESXI
LAN Port intel NIC > port 1 into standard network switch. ( not managed )
port 2 network switch > Onboard LAN port of ESXI server for managment.
The rest of the network ports of the switch are 2 Ubiquiti WIFI accespoint, and some computers.

As you can see, i also installed OpnSense just to find our of PfSense was the problem.
But also OpnSense has the same problems.

kiokoman

it's ok, was the cable removed during this screenshot i suppose? physical adapters are not green
if you are using igbn (native esxi driver) try to install net-igb (intel driver for esxi)

also install open-vm-tools from pfsense packages if you didn't already

marcel1988

Yes, the cable is removed otherwise i dont have good internet ofcourse :)

Both the drivers are installed:

Also the package in PfSense for open-vm-tools is installed.

kiokoman

idk, settings are ok, maybe do a backup of your configuration ad reinstall a new clean vm with pfsense 2.4.5 or try 2.5.0

Cool_Corona

Can I get a Teamviewer into the box... then I will have your ESXi/pfsense running in 5 mins

marcel1988

@kiokoman
I have tried freshinstall of 2.4.5 and 2.5.0
I have tried backing up and restoring.

Maybe te problem is the fact i dont enter a MAC-ADDRESS into the wan port of the T-mobile fiber?
and i leave the MTU also clear?

@Cool_Corona
if you can do it in 5 minutes. you can also tell me how ;)

kiokoman

that would be something specific to your isp

marcel1988

So i tried adding a MAC-ADDRESS but then there is no internet at all.
Where in PfSense can i find a log? so maybe i can see where the problem is occurring.

kiokoman

all logs are under status / system log
what kind of connection is it? pppoe ? dhcp? static or dynamic ip?

gcu_greyarea

I have a cable modem and for testing purposes I have been switching between a pfSense VM and physical appliances.

Not sure why - but my connection is stable with the mac address used when the connection was first setup. This may be a provider thing...

Either way - if you want your pfSense VM to use a custom mac address on the WAN interface you'll need to allow forged transmits.

I'd also suggest you enable promiscuous mode.

https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.security.doc/GUID-7DC6486F-5400-44DF-8A62-6273798A2F80.html

and

and

https://wahlnetwork.com/2013/04/29/how-the-vmware-forged-transmits-security-policy-works/

For good measure also allow mac changes.

Once its all working... you can revert these settings until you know exactly which setting breaks your environment.

To sum this up: on the WAN vSwitch and Portgroup you need to:

Allow Mac Changes
Allow Forged Transmits
Allow Promiscuous Mode
In pfsense - on the WAN Interface use a Mac Address that has previously worked with your provider

@kiokoman

These where my settings when i was using the Ubiquiti USG router:
