David, Greg, Is it not possible to have some private address space between the cisco router and the linux box ? sth like this: cisco 192.168.1.1/24 | | (possible hub/switch) | | 192.168.1.2/24 linux box So, everything comming from the ISP for a.b.c.nn/24 will route to 192.168.1.1 ? (I'm new to this, so don't laugh too much, pls ;) -kosio
