I originally sent this message to AmiTCP tech support, but they seem
uninterested in providing timely tech support to those who purchase
their software. If anyone can help me with this setup, I would be
greatly obliged.



I am using an Amiga 4000 with Warp Engine, 42MB RAM, OS3.0, AmiTCP
v4.2. I am using a ppp device to connect to my ISP, and it works fine.
I also use an Ariadne card to connect to two other machines in my
office. I would like to have the two other machines route through my
Amiga to the Internet.

My ISP has assigned our office several static IP addresses. In
startnet, I have AmiTCP use the ppp0 device. It works fine. The ppp
connection has the Amiga with an IP address of 199.45.83.163. I then
bring up the Ariadne card with IP 199.45.83.158. Both devices are
using a netmask of 255.255.255.0. A machine on our network has an IP
address of 199.45.83.162. Here's what happens.

With both devices online, the Amiga can see everything - the Internet
via PPP, and the local TCP network via ariadne. The Internet can see
the Amiga at 199.45.83.163, but not the ariadne (199.45.83.158), nor
any computer connected via the ariadne. A machine on the local network
can see the Amiga at 199.45.83.158, but can't see beyond that. In
other words, AmiTCP is not "bridging" the two devices, ppp and
ariadne. I have gateway=yes in the AmiTCP config file, and I did
everything I could think of with the routing tables. Nothing worked.

Could you suggest what the problem might be, and what I can do to
resolve it? I would also like to be able to use one IP address for
both the ppp device and the ariadne, but I am unsure as to how to
convince AmiTCP to route 199.45.83.162 through the ariadne if the
ariadne has the same IP address as the ppp device.

Thanks in advance for any replies.
