Hi,
I'm trying to make a private IP CT access the Internet with no success.
My CT has been assigned two private IP addresses, the first one 10.0.0.X needed to access other CTs on the same HN in the same IP network class and another IP 172.31.1.x to access a private LAN connected to eth1 on the HN
The container access to both networks quite well, however now I need to make it access Internet withouth assigning a public IP (I don't need accessing the container from the Internet).
Can anyone explain how to configure the networking in the CT and/or HN ? I tried the solution posted in howto (SNAT) but it's not working in my case.
Current CT networking setup is the following:
