With ICG version 2.x or 12.01.x and UMS version 6.x or 12.01.x, it is not possible to inspect the TLS traffic between any of the components. The inspection would break TLS and interrupt communication between the products.
As of UMS version 12.02, you can inspect the TLS traffic, see Universal Management Suite > UMS Articles > IGEL UMS Communication Ports > IGEL Universal Management Suite Network Configuration > Configure the UMS to Integrate Reverse Proxy with SSL Offloading.
