Although you'd probably have to modify the example from the LARTC HowTo this should work fine. We can probably supply suitable ethernet cards for the hard of networking free, if they prefer to do it physically the same way it is logically. Doing it phsyically is probably more secure if you make the Linux box into the firewall. Indeed if a network has 2 routes to the Internet your client boxes (at least the Linux ones), could be configured with both of them as default routes with the same or different weights. Of course it is important they are configured to only use one route per single TCP/IP conversation if the routers perform network address translation. -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
