WAN requiring root CA to be installed for internet access

reqman

@johnpoz you're da man!

@johnpoz said in WAN requiring root CA to be installed for internet access:

You should be able to add the CA to the trusted certs that freebsd trusts.

Can it be done from the GUI? Any info will be appreciated.

johnpoz

@reqman should be yeah, not sure if available on 2.6?? But on my 23.09 here, this checkbox should do what your asking. You would import your gov CA, and since added to the os trust, when pfsense checks for packages, updates this would accept your gov mitm cert they issue for the fqdn used.

stephenw10

You can just set the check box when you import the CA cert:

Edit: Ooops took too long to reply. What he said.

Also, yes, that option is in 2.6. But you should still upgrade.

reqman

Well, on 2.6.0 the screen is a bit different:

The upload went just fine:

However, trying to even check for updates fails, with a reference to the cert:

You may have to add the proxy explicitly to allow that to work:
https://docs.netgate.com/pfsense/en/latest/config/advanced-misc.html#proxy-support

Try running pkg-static -d update to get more error output though.

Hmm, use it to support the normal update mechanism I suppose, right? I could try that I suppose, but I'd rather do the update manually via ISO, if that is possible.

Try running pkg-static -d update to get more error output though.

Sure:

Hmm, it would interesting to see what the cert the proxy is sending shows as when pfSense tries to access it.

But just reinstalling 2.7.1 will work fine as long as you don't need to install pkgs.

reqman

@stephenw10 my apologies for delaying to reply, suffering from the not-having-enough-free-time syndrome.

Which would be the safest way to upgrade my installation to 2.7.1? Fresh install from ISO and import saved config? Have an ISO mounted and launch a script of some sort? Other?

Gertjan

@reqman said in WAN requiring root CA to be installed for internet access:

Have an ISO mounted and launch a script of some sort?

If your pfSense is a VM, yes.
Reboot the pfSense VM machine, and is should boot from the ISO? where the pfSense installer takes over.
Another classic one : No VM, so prepare a USB drive. See pfSense documentation about how to create one. Use "etcher" as told.
Boot from the USB drive : the installer takes over etc.

If the installer finds an already extiing partion with the (old) 2.6.0) installed, it will use the config for the new setup.
If not, no issue neither, just use your daily backup of the config file.
Just finish the install with a minimal setup like : define LAN and WAN. Now the GUI is available from LAN. Login, and in the GUI, import the config. Have it reboot.
Done.

@Gertjan took me almost a year to schedule some downtime for this device. Downloaded the compressed ISO of 2.7.2 (iso filename is netgate-installer-v1.0-RC-amd64-20240919-1435), mounted it to my pfsense 2.6 CE VM, enabled booting from the VM CD and fired it up. For a moment I did not understand that 2.7,2 actually booted TBH, until I noticed the "+" next to the pfsense logo :) . Did not know what to select at boot so I just let it take its path.

Unfortunately, a bit later the VM shutted down by itself. Tried the exact same procedure, but no go.

FYI host is a free ESX 5.5 hypervisor on an Xeon E5506 (yes, I know it's old).

Seems I'll be stuck with 2.6.0 :)

That 'ESX 5.5' is probably the issue right now.
Check for yourself : install pfSense 2.7.2 on ESX 5.5 hypervisor and you won't find anybody talking about "5.5". It's version 8 or 7 if you have to.

Ok to keep old software. But mixing new stuff (pfSense 2.7.2 uses FreeBSD 14) on old stuff, is like installing windows 11 on a PC without a TPM : you can (probably) force it, but it needs uncommon knowledge to do so.

stephenw10

You can enable the CE repos in the Net installer and install 2.7.2 from there.

Or you can install 2.7.2 using the legacy ISO image.

But, yes, you may find that ESXi version is too old to support it.

The problem is likely the vmxnet3 driver. Change your virtual machine to use the e1000 NIC driver and try again. You will take a performance hit using the e1000 virtual driver, but that should let the newer pfSense boot and run.

I had this problem with a generic FreeBSD VM I had a couple of years ago. The newer FreeBSD versions have an updated vmxnet3 driver that apparently does not play well with older ESXi versions. Changing my VM to use the e1000 virtual NIC allowed it to boot and run. If the NIC driver is the problem, the machine crashes and reboots when the NIC driver loads. So, the machine starts booting and looks good, but then crashes when the NIC driver is loaded.

I know, but the iron does not support 6.0 and later.

Very useful info, thanks. Will give it a try, when I find some time to reschedule this experiment.
