Looks like a good update.
It does share the code from #549 , so lets get that merged before progressing/testing this PR.

Having trouble getting this working as intended.
Will need to spend more time having a look tomorrow.

On the deployTab we need to extend the inclusion of aksOutboundTrafficType parameter to include custom networking model

Works as expected.... great job.

It'd be cool to add a new related feature so we can give users the sample config for putting in the DNAT to Azure Firewall to properly expose ingress. Could be a sample page, a blog, etc.
