A bit of an odd one here (and has been reported to Ruckus as something that either needs clarifying or fixing) in that if you want to remove the requirement for CAPTCHA when self registering in a ‘out of band’ workflow block you need to configure your own SMTP server. Now that’s all fair however even with the server configured the disable option still doesn’t appear.
In this case it looks like you also need to disable (or configure yourself) the built in SMS server at Administration > System Service > Outbound SMS. With that set the disable option then appears in the drop down.
After a few years on hold it’s great to be back at CITC this time in the British Motor Museum. The video presentation covers a short (if speedy) introduction to Node-RED and it’s ability to integrate systems through their APIs.
Demo 2 is of note and shows how a user visiting a malicious website can have their internet access revoked until a helpdesk agent has a chance to clean-up their machine and then grant access again without even having to login to the firewall controlling that access.
A little treat that I hope will help someone at some point, for those with Palo Alto Networks Next Generation Firewalls (NGFW) and Aruba Instant Wi-Fi you can forward syslog messages from the controller to the NGFW and parse them with the profile below to map users to IP addresses.
There is plenty of information on syslog to User-ID at this link for those just getting started: https://docs.paloaltonetworks.com/pan-os/10-1/pan-os-admin/monitoring/use-syslog-for-monitoring/configure-syslog-monitoring.html.
The text strings you will need are:
- User authenticated
AADSTS700016: Application with identifier <Entity ID> was not found in the directory ‘<Directory ID>’.
The fix here is easy – the GlobalProtect client injects a :443 at the end of the domain name which isn’t mentioned in the guide from Microsoft (https://docs.microsoft.com/en-us/azure/active-directory/saas-apps/palo-alto-networks-globalprotect-tutorial) but is in the guide from Palo Alto Networks (https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g0000008U48CAE).
Interestingly the Reply URL doesn’t specifically require it (although mentioned in the Palo Alto guide) but either way easy to fix.
Having recently moved home I have become a part of the privileged few (hopefully not for long) in the UK to have fibre-to-the-home (FTTH sometimes known as fibre-to-the-premises or FTTP). Not wanting to use the EE provided all in one modem/firewall/router/switch/access point I have a setup that uses the pre-installed BT Openreach Nokia modem (ONT) a pfSense firewall/router along with a Ubiquiti switch and (eventual) pair of Ruckus wireless access points.
From the BT Openreach modem a copper cable (probably Cat6) connects to the WAN interface on my pfSense firewall. EE provide some guides (see links below) that provide some handy pointers but don’t answer all the questions.
Working out your username (and password)
As described in the guides your username will be in the format PRODUCTIONHQNUN<NUMBERS>@fs after a little bit of poking around the username is the same as the EE account number which can be found at https://mybroadbandaccount.ee.co.uk/b2cselfcare/b2c/myaccount > select your active account > it’s the number in the round brackets.
For example the username based on the (redacted) account number as shown below could be PRODUCTIONHQNUN48123456@fs.
Your password will have been set when you first signed up for Broadband/your EE account (if you have changed your EE account password since first setting it it’ll likely still be the first password set). If you can’t remember this or don’t know it you will probably have to call 150 to see if it can be recovered (or changed).
Plugging it into pfSense
With this information in hand hop into your WAN interface on pfSense and configure as shown below. Firewall/NAT configuration is out of the scope of this guide but the defaults configured in pfSense will normally work well as is.
With a view to make life a little easier for the next person I’ve included some sample config below which can be used with the Waveshare E-Paper ESP32 and ESP8266 Driver Boards (of note are the pin configurations and the platform type for the ESP32).
I’ve also found that as mentioned in the documents the 7.5″ v2 display really does require an ESP32 to drive it even if you’ve managed to get it working with other projects on the ESP8266. Additionally the ESPHome-Flasher tool delivers much more consistent results on an ESP32 when performing the initial flash.
It’s been a while since posting and I do hope to sort that out but for now another quick mention of some work with Ruckus Cloudpath.
Although massively flexible in its design I’ve come into a few niche cases where administrators would like a single DPSK pool (which is bound to a single SSID) but where different users have different expiry dates on those DPSKs. Thus far I’m planning on interacting with the API via Node-RED to update these entries in the API as the provisioning process takes place – something for another blog post.
However for those who are just getting to grips with the API (using PowerShell in my case) I hope the short example in this GitHub repo can be of use: https://github.com/jamesfed/RuckusCloudpathAPI.
Ruckus Cloudpath is quickly turning into one of my favourite add-ons for a wireless network in a residential/University setting. It’s doing this by letting users bring all manner of ‘smart’ devices into an ‘enterprise grade’ network and connect them securely with a personal WPA2 pre shared key.
Even better Cloudpath has loads of options for customizing the onboarding portal – the little tutorial below shows how to change the colour of the font in the footer of the page with a custom CSS file.
You may find that when doing decryption on a Palo Alto Networks Next Generation Firewall that images in Slack channels are not displayed or are only shown in a very low resolution – in addition images cannot be uploaded. When inspecting the HTTP error messages in your browser a 503 response may also be seen.
To top off the issue you may also see that User-ID isn’t mapping traffic from the Slack desktop application against the traffic which negates any User-ID based decryption exception you might have.
While helpful the Slack connection test tool at https://my.slack.com/help/test also doesn’t appear to throw any errors.
To fix this issue you need a decryption exception custom URL rule for the files.slack.com domain (which fixes viewing images) along with the base domain for your Slack tenancy (fixes uploads). This domain can be found by clicking the drop down in the top left corner of the Slack client.
If you have multiple Slack tenancies then you will need an exception for each one.
As always when making exceptions for your decryption policy please consider how it might degrade your ability to detect malicious usage of the network – in this case the sharing of files with unknown payloads.

XML: The returned XML does not match the expected schema. (code: PE233) — JSON: The returned JSON does not match the expected structure (Invalid JSON.). (code: PE231)The cause is the default encoding from PowerShell is UCS-2 LE BOM as shown in Notepad++ below. The fix is simple in that when generating your REST configuration append -Encoding utf8 at the end of the Out-File command. I’ve also seen this apply to a few other situations when using PowerShell to output some form of text – in particular feeds for Palo Alto Networks Next Generation Firewalls.
