Probably all you need is an Ethernet switch, though there are |
34 |
some DSL modems that have been intentionally crippled in an |
35 |
attempt to make them work with only a single client. |
36 |
|
37 |
My sister has one. It will support a /16 internal network just |
38 |
fine except that the DSL modem's DHCP server will only hand out |
39 |
a single address (and there's no way to shut off the DHCP |
40 |
server so you can let something else take over). You could |
41 |
fill the house with machines as long as they all have |
42 |
statically assigned addresses. |

If you do want something else, you can add a second |
49 |
firewall/router, or you can probably replace the 2210 with |
50 |
something a bit more configurable. I've installed a couple |
51 |
Zoom DSL modems. They work fine, and were fairly configurable. |
52 |
|
53 |
What would be coolest would be something supported by OpenWRT, |
54 |
but I was never able to find such a thing. |
