Has Anyone Been Able to Disable CGNAT with O2?

[CasuMartzu]

I'm trying to setup a site to site VPN using a cradlepoint 5G router feeding a Pfsense firewall and coonect it too a Fortigate device. As far as I can see, it's all setup correctly but fails due to the CGNAT in use at O2. This is on a business account but Premium Support aren't answering and out account manager is saying go and use Akami AccessMyLAN.

Can't beleive I'm the only person in the world to try this so, has anyone had any success with it?

You can't disable CGNAT on anything other than an Enterprise Contract with a Private APN, as you at this level are routing data over your own Internal Network and out of your Internet breakout. 

I am sure your account manager would be happy to provide a quote, and VMB will be happy to help...
