http://ubuntuforums.org – Hi, I'm running Ubuntu 12.04 LTS on a system with a wired network adapter (eth0) and a wireless adapter (wlan0). Both these adapters are connected to a different network with internet access. Is it possible to use wlan0 for internet browsing for example, and to run an apache webserver on the eth0 adapter?
