Laptops reporting to ERA from internet

[kubasz 0]

I've got simple questions:

1. For managing ERA Agents installed on laptops that are in internet, should I use ERA Proxy with 2222 port exposed on internet which is comunicating with tcp 2222 ERA server?

or

2. Should I only expose 2222 port of ERA Server to internet?

 

In case 1  Proxy would be in DMZ, and ERA Server in LAN
