Re: Combining 2 Ethernet NICS -> 1 IP address
I'm not a network guru but I think bridgeing can do this. brctl is the command you use to bridge two interfaces. Maybe a search on google for that will turn something up? apt-get install bridge-utils should download all the packages you need for a 2.4 kernel. Some one please conrrect me if I am totaly off track here as I'd also be interested n this kind of thing.
