Thank you for the detail summary Kolla.
However, I am still unable to access Internet from my browser...thoughts on next step?
I assume you're testing the browser's connection to the internet by entering a site name rather than an IP. I didn't see a mention of DNS earlier in the thread, but you'll need to point the amiga to a DNS server to be able to resolve domain names.
Try pinging an IP on the public internet, such as 8.8.8.8, from the amiga. If that works, then your routing is OK.
