My Leopard machine acts as the Internet gateway for the rest of my network since I use a USB based EVDO dongle for my Internet connection

->-(ppp)- Internet on Mac (en0)->- Router --> LAN systems

Now I need to forward some ports including port 80 from the Mac ppp connection to the Router (one of my LAN systems runs ubuntu and acts as a webserver + some other services)

Unfortunately, the Internet sharing application in Leopard is quite crippled and barely allows me any configuration options

Any pointers please?

Welcome to our forums!

If you have a router, why don't you set up the port forwarding on it?

"I use a USB based EVDO dongle"

The router is probably just acting as a switch.

"Probably." The OP doesn't say.

^^ Actually , I did

The router can (and used to forward ports as expected before I switched from my DSL provider (poor service speeds..less than 1/2 mbps) to the new EVDO service provider (averages over 2 mbps)

Just because you use the USB EVDO dongle for your connection doesn't mean that the router was being used as a switch. All packets still come in, go through your machine, through the router, and go to the other machines. I don't see why you don't just continue using port forwarding on the router.

Because that wouldn't solve his problem, with another router (the iMac) upstream of the router. He'd still need to do the port forwarding on his iMac, which is providing NAT services.
