After configuring SEPM to connect to ATP appliance, the SEPM external communication setting Private Cloud is enabled to use Advanced Threat Protection servers fro insight lookup and submission, also it has use Symantec sercer when private servers are not available.
This is expected and good.
However, I noticed that my proxy server using custom proxy setting information were completely removed, is this bahior by design? I am afraid it might be a bug, SEP client will use Private Cloud setting if SEPM is configured to connect to ATP, that set will take precedence over the proxy server setting, but wipeout the custom proxy setting is not necessary.
Another issue I noticed, if I put back custom proxy setting, even though the provate cloud setting still enabled, the SEP client no longer communicate with ATP appliance.
Does anyone have the similar setting experience the same issue? Thanks
