Guest#1 can access to the internet on my WindowsXP host.
I can ping from or to Guest#1 and Guest#2.
then i try share the internet to Guest#2.
Guest#2 can go out to the internet.

Case 2:
IpCop as Guest#1 have 2 network adapter .
I attach network adapter#1 to NAT (10.0.2.13)
and network adapter#2 to Internal network.(192.168.16.3)

Windows XP as Guest#2 have 1 network adapter .

I'm not sure my Guest#1 can access to the internet.
I can ping from Guest#2 and Guest#1
I can access Ipcop webadmin. (http://192.168.16.3:81)
i have to copy add-on files to IpCop by WinSCP.
but i can't connect from WinSCP to IpCop server by port No. 222 <----(Default Ftp port No. for IpCop)
i got this "Network Error: Connection Refused."
Please give me idea.
Thank you.

Your network settings look OK.

I have smoothwall, not ipcop, but they're very similar. And I have a Linux guest not a windows one, and they're very different! Are you sure windows firewall on the guest is not blocking the winscp session?

You need to enable ssh access to make winscp work - in smoothwall v3, this setting is in the admin gui under services > remote access.

eta: These are just suggestions - the problem might be something else
