Amiga 2000 PPP Internet Raspberry Pi

Have you read the comments on the blog?  Pretty much explained there.
Also use a dedicated subnet for your rpi/amiga network.

You don't need to configure this on your router.

I just noticed that you chose some odd addresses for the rpi/amiga connection which makes me suspect you are using the same subnet as on your network.

Let's say your network is 192.168.0.x

On the Rpi, use IP 192.168.1.1
On the Amiga, use IP 192.168.1.2 with gateway 192.168.1.1

The Rpi will route traffic from 192.168.1.x to 192.168.0.x.
I have spoken with the author earlier and can ask for his assistance if you still can't make it work

What desiv said.  The Pi will have 2 IPs, one for your Amiga/Rpi network (locally) and one for the network you have the other computers connected to.  The Amiga won't be able to tell.

Let me know how it works out

> have to tie into my router

You don't.  The RPi will act as a second router and take care of all that traffic.
I've sent a request to the author of the jmp.no blog to make a step-by-step tutorial.
