Once you request your SSH credentials to login to your containers the system will return you an ssh username with private ip addressing.
In order for you to be able to access these IPs we have mapped them to public ones. 

This is the IP address map list

10.1.3.3 -> 78.159.126.56
10.1.3.4 -> 78.159.126.57
10.1.3.5 -> 78.159.126.58

Example:

If your system give you this username: fc249e6dd246c6bf142415be95e444@10.1.3.5 then you need to change it to fc249e6dd246c6bf142415be95e444@78.159.126.58
