[Blackburn] ADSL (again)

[Stephen Taylforth]

Linux and USB is a grey area, Its far easier to use a router with a cat5 connection. You don't need a second IP for a Web server. There are two ways of doing it with one,

Option 1, If your web server is the same machine as you surf on or is what you use as a gateway to the internet for other machines on the network:

Give the lan card in your server the IP address and use the router as a 'Bridge' - ie it isn't really acting as a router, its a glorified modem that knows all about connecting to the internet itself and just passes the stuff straight through to the Lan Card in the web server which then does the routing if nessecery.

Option 2, probably the easiest to sort.

Give the router the IP address and have the server on the network with a private IP address (192.168.*.*) and set the router to route port 80 (web) to the IP address of the server.  So that any requests for port 80 arrive at the router via its Internet IP and the router then redirects it to the private IP address  of the web server. 

Any router worth its salt can be set up in either of these two ways. The DLINK DSL500 (1 ethernet port) or DSL 504 (4 ethernet ports) are easy to get hold of at reasonable money and will do the job (65-80 quid + vat).
