hello, these are my naive questions, I am a newbie:
I need to firewall my homebrew linux boxes, say to close everything I can to/from outside (internet), and do
everything inside my vpn. On the FIREWALL machine I also run some server whose services/ports must keep to be
accessible to/from outside. Those kinds of connections I need to do also to servers outside.
All the machines of the VPN need to be free to suft the outside internet. So also masquerading and forwarding are
needed.
thanks a lot for your help,
Andrea
That's my box: (see also below for explanations)
